I'm looking for some E7s that have been professionally ported by someone who knows what they are doing. Heads like Thumpers or Powerheads would be nice but I'd like to find a pair in the bay area if possible.

If not, are there any reputable places to go to have the work done? Any idea on costs?
TIA

Why are you looking for stock ported heads? You're better off spending a few hundred more for some TFS TW's or something. TFS's flow more out of the box than stock ported heads will ever flow unless you do some SERIOUS work like welding/epoxy/crazy valve job, ect.

All I'm looking for is a low budget, low RPM, high torque, smoggable street motor. It would be a waste to spend over a grand on heads since I don't race. I'm looking to spend only about $500 for heads thats ready to bolt on using exsisting stock valve train. I might splurge and go for the CCM GT40Ps. We'll see...but if I can get something local thats even better.

You're better off with the GT40P's.

you can't shake a stick at the # of iron GT-40s for sale in the auction block on the corral. $400 is average.

GT-40P's are still available in wreckers for about $200-$250 if you can find them.

I am a new fan of the iron GT-40
Added 4 tenths and 4 mph to my car compared to when it had basically the same boltons but E7TE heads, plus my car is heavier now by about 100 #'s and lost driveline efficiency (spinning a tremec 3550 vs. a T5)

If you're still set on porting stock heads, don't take it to anyshop in this state, or the west coast for that matter. Check out the Trophy Stock racers in the NMRA, see what shops are doing the heads for the successfull racers and talk to them.

Just get some aftermarket aluminum heads like AFR 165's or 185's then youll flow better and shave about 40-50 pounds off teh front end of your ride.

Did you see the January '03 issue of MM&FF? They swapped on some Power Heads ported E7's ($881.64), Trick Flow street intake, Anderson B21 cam (anyone have specs? Prolly ~220 @ .050, .512 lift) 76mm MAF, 70mmTB, 19lb injectors. Stock , dyno at the wheels for this AOD car was 197hp/256tq. After the awesome CNC ported E7's and supporting cast- 238hp/273tq. Whew- hope you were sitting down. They did say the stock mufflers were holding them back. Think it had a BBK cat pipe. And before you dis the stock injectors, I went 12.51 at 109.45mph on 'em. If 230-250rwhp is enough for you, then the Power heads can get you there...
reported flow numbers, 215/175.

I have a set of these heads on my new 347. They are great, and as soon as I figure out what I am going to do about an intake then I will get it to the dyno. My car is a tank 3500lbs without me, so I am more concered about low end torque, and let me tell you the 347-CNC-E7's-E303 seems to be making a lot of it even with the stock intake, injectors and MAF. This car wnt 14.9s before the new motor, and now I am sure that it is in the mid 13 area. Can't wait to feel what a good intake, MAF, injectors and tune will do.

I friend of mine at Flowmaster ported my stock heads and I got a valve job done and they are flowing a little better than an out of the box iron GT-40. I will be putting the motor back together by mid December and take it to a chasis dyno with the new motor (306). I also added a mild crane cam.
 
Posted by TOPnotch (Member # 1340) on :
 
Yeah don't let these people perswade you to spend your money where its not needed. The Gt40 heads are basically the same thing as stock ported heads. I am going to be running some ported E7TE'S on a 302,e cam, and a systemax intake and all the bolt ons I'll let the board know how it does. [Big Grin] [burnout] [burnout]

Are ported E7's better than stock? Absolutely. Are they worth $800? Hell no. If you can get a good deal on someone porting them, then go for it.

I took my heads over to my friend just to get the exhaust bumps grinded off and he wanted to se if he could get them to flow as good as some GT40's they had just flowed. 2 months later they look pretty damn sweet and flow good as well I guess. Plus it is a cool sleeper mod. I am going to kick him some money, with the valve job and porting, I will be into them for less than $300.
 
Posted by Fox89GT (Member # 1539) on :
 
Yea, I also agree that ported E7s are not worth $800. I think I'll hit the junk yards for some Explorer Ps, have them cleaned up a bit and use those. The GT40s sounds good too but I was leaning towards the Ps due to higher flow velocity. I figure this is good for lower RPMs. Besides, the Ps have smaller chambers for higher compressions, which is also a plus.

Now for a budget cam...

I'm sorry but a 347 in the mid 13's just doesnt impress me at all.

It is a good thing that I am not trying to impress you. If you would like we can set up a race, and see if my not so impressive car still doesn't impress you after a 1/4 mile pass.

I'm more impressed with the GLH of yours [Big Grin] (seriously)

It is a hell of a car. I have had more fun in that car then any of the other cars I have owned.

Goes Like Hell! Wish I had kept the wife's Horizon and done the turbo kit from MOPAR. Would have been a cool sleeper.

I have to say, if you're on a budget and you want "professionally" ported heads, it isn't worth it compared to after market heads of today. A true "pro" isn't going to port heads for $100. You are looking at something more like in the $600 area for the porting PLUS the cost of the valves, hard seats, springs, machining, installing screw-in studs and guide plates and all of the other components of the heads. It just isn't worth it these days to use stock casting heads for performance use.

If you still want it to pass smog, then opt for a set of CARB legal after market heads and you'll still be ahead of the game.
 
Posted by hidnn.o.s. (Member # 1219) on :
 
Not entirely true. It depends on who you know and what tools they have. I got my heads ported and a valve job done for less than $300 and they out flow a stock set of GT40's.
 
Posted by theguywhoknows (Member # 2148) on :
 
REAL porting takes at least 10 to 15 hours of hard grinding time. A "Valve job" isn't "rebuilding" the heads and no "professional" works for free or cheap, and on top of that, GT 40 heads don't flow very well to begin with... compared to most after market heads out of the box anyway. It just isn't worth it to mess with cast iron, stock casting heads anymore.

Cough, Cough, you are wrong Cough, Cough.

Did I say that he did a valve job only and they are great? NOOOO, he has had them for about 2 months slowly working on them at work and flowing them as he has gone to see what he could get out of them.
 
Posted by hidnn.o.s. (Member # 1219) on :
 
I am not just looking and saying "ooooh, these are smooth. Must flow good" I don't even have them. I am going by the numbers that the flow bench is putting out. And GT40's are great heads for the money on the average low budget racer.
 
Posted by theguywhoknows (Member # 2148) on :
 
You said, "I got my heads ported"
and
"and a valve job done for less than $300"

That tells me you have a valve job and some porting for less than $300.

That isn't very much considering... good springs $80 a set, new "good" valves $145 a set, good locks $15, Powdered metal or Tungston hard seats $20 plus installation, Viton seals $8.00 (stock type), surfacing $40. That right there is over $300 and we didn't even get into good retainers, screw-in studs, new guides, machining-off the stock stud bosses and power tapping, guide plates, CC'ing the chambers, porting, enlarging the spring seats and so on. That's all I was looking at...
 
Posted by hidnn.o.s. (Member # 1219) on :
 
Consider this. If the place it is being done at has a flow bench it most likely isn't some random garage. It is obviously a friend doing it for me, and it has taken 2+months because I am in no hurry considering the deal he is giving me. Porting and stuff is what he does. he works in R&D at his company so parts are all around and what he doesn't have he can make a call and tell them the project he is working on and get things for next to nothing (litteraly).
Regardless, all I am saying is that I have a set of stock heads that outflow GT40's out of the box for less than $300. GREAT investment. Great sleeper mod.
 
Posted by theguywhoknows (Member # 2148) on :
 
Yeah, you're right... I have a Super Flow 601 too. I was just taking it as an average "Joe" that said he can get his heads "professionally" ported and rebuilt for under $300 and in any case other than your's, someone would be dreaming. A good port job with flow numbers can easily run $600 to well over $1,000 not including any parts. When we have heads CNC'd, it is even more than that.

I just took what you said at face value is all. No worries. Still, I have to say though, out flowing a set of GT-40 heads isn't that hard when Dart Windsor Jr's, Edelbrock RPM's, TFS's, AFR 185's and so on will do it even better with better combustion chambers, higher velocities, more flow and better swirrel, plus the majority of those are aluminum, which is much better than cast iron right from the get-go. But if someone is on a budget and wants GT 40 heads, more power to them. I just like seeing money go further and these days, spending anywhere from $750 to $1,100 for a "nice" set of after market heads isn't that much considering what you get as far as features and how much "bang for the buck" you get. I figure if someone's going to spend the $ on professional porting (on any heads) they should be getting at least 270cfm @ 28 HcI on the intake side, and that is pretty hard to do with stock castings because you just can't fit that kind of volume through X amount of area (in most cases) without ending-up in the water jackets. Glad to hear you have a good friend that is willing to help with the porting because I can say first hand that I have spent literally thousands of hours over the past 25 years porting heads for hundreds of customer's and it still sucks, even to this day! Ha-ha-ha! What a dirty, noisy mess and your back after you're done? Forget about untying your shoes after an 8 hour day of porting... don;t even try to bend-over... just kick 'em off and go lay down. I like CNC'd heads more and more as I get older :-)
