stock '95 302 short block
B-cam
1.7 crane cams rr
Edelbrock performer heads
150hp nos wet kit* (may, or may not end up using use)
Which gasket should I use?
Fel-Pro Performance Z10111 .041 in (already have)
or
Fel-Pro Performance Z1006 .039 in (twice as much money and wire loc)
I want to know if it matters which one i use. i know if i use nitrous it probably does matter.
lmk.. thanks, mike

Adding a pre-flattened ring around the combustion chamber raises the sealing force to roughly three times that of a standard head gasket, and allows the gasket to withstand combustion pressures from 1,500 to 3,000 psi in engines generating over 1,000 horsepower, Some performance head gaskets have oversized wire rings around the combustion chambers that act like O-rings to improve sealing. These require machining receiver grooves in the head or block to accommodate the wire.

Well.. I have that groove on my heads, and I am wondering.. If I do use a gasket which does not sit within that groove.. will this compromise my sealing capability of the gasket..?

The wire rings help concentrate loading around the cylinders to prevent combustion pressure from blowing past the gasket, Personally i think its fine they are lockwire head gaskets but any other idea's people?

If you are machined with receiver grooves then run loc wires.

He has the receiver grooves and bought lock-wire gaskets but he doesn't see anything protruding up around the combustion chamber on the gasket.

Well, It does have the metal ring around the combustion chamber, but.. it is not a wire loc ring. It is a pre flattened ring. as Dan suggests I should use it. I also think the same, I just wanted to see if it is a waste of money. ..you just want my car to blow up so I you won't see my tail lights Anthony ![[Big Grin]](biggrin.gif) .

A pre-flattened wire ring is so that you don't have to have the wire ring pressed into the bottom of the head, ones that protrude crush down so the pre-flattened ones are already crushed.
Edit: spelling

Also, if you going to be shooting nos your better off getting the copper head gaskets but than you will run into leak problems because they do not seal oil and coolant very well. If the engine does not contain any coolant, coolant leaks are not an issue. But for engines that do run coolant, getting a copper head gasket to cold seal and maintain a seal can be a challenge.
p.s dont F*** with me man i know my sh*t LOL!

I am not 100% sure what you guys are saying but I can tell you that if you run loc wires you need the receiver grooves machined into your heads.
I am not sure why you would want to run a non loc wire head gasket if you have the receiver grooves machined, other than cost. I have honestly never ran a standard head gasket when the heads have a receiver groove machined in them, if you can do this at all, I do not know.
I do know that a copper head gasket is not a good idea for a street car. It can be done but I have only seen this on one street car and it was a borderline street car that went 6.0s in the 1/8 with a TRW piston so it came apart and was inspected regularly. This was also in alabama so we know how them redknecks are!! J/K. Im a red kneck too if you get down to it.
Anyway you shouldnt be running anything but straight water at the track anyway it is just too hard to clean up coolant/anti freeze.
I know, I know everyone does it but I do believe it is enforced at sanctioned events.

On another note and not to point anyone out ![[Roll Eyes]](rolleyes.gif) but if you are relying on a headgasket to keep the combustion process in check for a shitty nitrous tune or a shitty tune, period then I think you will end up very very disappointed.
Sometimes it is nice to have a headgasket blow (rather than a ring landing be gone or torch hole in your brand new AFRs) when your engine begins skipping at the end of the track and you take it home to pull it apart and it is just a blown head gasket. It is a great learning device for when you are tuning your car and are very novice.
