From his profile, it appears he has a 65 Mustang. Possibly transplanted a roller 302 into it.
The combo you've listed is the way to go. Make sure the spring in the vac secondary is working to it's full potential. Also, with those headers, full a 2.5" exhaust system and a good set of free-flowing mufflers.
If you want a carb and intake cheap, I've got nearly the same combo sitting here.

I already have my parts. OH and sorry I always confuse people with my set-up .
Yes I converted to carb and ditched the Fuel Injection. Mainly because I wanted to get my car up and running and didn't want the added trouble, time and money, for an ecu wiring harness.
Say what you will I dont really give a sh*t! I wanted to do it ol school I dont care about trouble with cold start and the small mpg gain. Plus the benefits of the H.O block (aside from roller cam) made my $300 dollar purchase of the engine a smart choice.

OH sorry if I sounded pissed people always are hassleing me about not going EFI. Also I plan on going with a pair of magnaflow mufflers because from what I have heard and been told they will give me a nice deep sound. Also for piping size I wasn't sure what size 2.5" as JohnB I had in mind. Would a 2.75" be too much or too loud. I want to be able to not get pulled over all the time but still sound Bad A$$! Also would a 2.25" be too small.

Whooooaa...throttle back turbo, no one's talkin' smack about you. It's all good...
Stick with a 2.5" exhaust. It will be plenty for your setup. Mufflers, not pipe diameter, will make all the difference in your application.

OK, I did a similar set up for a friend that had an 85 H.O.. Same long tube headers, good cam. He didn't want to spring for a good set of heads so I ported his heads and put in chevrolet 1.94 and 1.60 valves. We put a 331 stroker kit in it. No dyno infomation but he reported back that it was sufficient to beat at least 2 vipers and one 06 corvette. I think both of those beasts are capable of 12 something in the 1/4 mile.

Dual 2.5 pipes with a crossover pipe to equalize exhaust flow.
