My l48 build thread
Well im starting over my build with my new corvette i get hopefully monday shipped to me from St. Louis 
I already have:
2101 performer intake
timing chain
recurve kit
lunati voodoo cam 262/268
lifters
felpro gasket kit
new rocker arms
so basically all I need now is my heads. This is where you guys come in.
What would be the best combo with my current gear to get hopefully 350hp or 300hp. As in what aluminum 64cc heads would do it.
Elderbrock E Street heads?

Check out Pro-filer heads. Do not confuse them with the controversial pro-comp heads. They are not the most well known, but very high quality, great price, and are suppose to rival AFR's, some claim even better.

You're building your engine backwards, dude! You're supposed to pick out your heads, and then pick the rest of your parts to match them. But, it's too late now, so you have to do it the other way around. I think things will still work out for you, though. A 23 degree, 64 cc combustion chamber, 180 cc intake port head with 2.02" intake and 1.60" exhaust valves should be fine for your build, and are pretty commonplace. Also, go with the straight plugs. Are you going to use the Felpro 1094 head gasket?

2101 intake will not go with vortec. And, from my research, there is not a vortec intake that will fit under C3 corvette hood with stock air cleaner assembly.

Im aaware of how to build it. I had built everything around speedway heads due to lack of money but now I can spend a little more and want better quality.
I think ill get the pro filer heads
Yes I am using felpros gasket. Already had it ordered from my last build thread

You might want to look at the Brodix IK180 heads as well. Also, if using the stock pistons, look at the Felpro FPP-1094 head gasket that has .015 compressed thickness . . . will bump the compression up a little. I saw you said you already bought Felpro but wasn't sure which ones.

I have this
So for the heads im looking for 23angle, 180cc intake port, 64cc combustion chamber with 2.02" intake and 1.60" exhaust valves, and straight plugs
Also its paired with a voodoo cam 262/268 so I'm liking pro-filer heads

With regard to the angled plugs, about the only thing I can think of is that if you went back to a stock look with the iron manifolds and everything else, the shielding wouldn't fit. I had no regrets.

Also...*sigh*...angled plugs are the ones that interfere with most headers. The stock heads have straight plugs. Most headers are designed to fit the stock heads. So, you want heads with straight plugs.
I'm going to try out the speedway heads, but that's me, I'm a cheapskate, and I don't mind taking a chance. If you want a good aluminum head for a reasonable price for what you're buying, it's tough to beat the Dart SHP 180cc heads, they are about a grand for a set.
