i will be using exhaust manifolds, i will get a intake with a oil fill tube, air cleaner, etc.
Would i have any problems with vortec heads, what other heads if i dont use Vortec?
Aluminum heads? Can you paint these to match block? Does it hold? Thanks
400hp with those manifolds will be damn hard to do. You need a set of non-vortec heads, your choices comes down largely to budget. There's a lot of good offshore 200-210 castings that will work fine and be cheaper, then there's some good Brodix, AFR, Dart, Profiler, etc stuff that works well but costs more. Your head selection will NOT be the limiting factor, those exhaust manifolds will be. Since you're basically cutting your leg off before the race I'd just go with a good mild build. You will need a custom cam if you want that engine to be worth anything as those manifolds will change your needs from what s normally seen.
FWIW, exhaust manifolds are usually the FIRST thing to get rid of, and they are used as a RESTRICTION in many budget classes of racing.
