Guys I want to build one mean ass LT1 or LT4, that will take any mildly modded LS1 and maybe a few heavily modded ones. What would you guys consider the best LT1 or LT4 head that can be used on the street. I want to have really good heads then I wont have to have such a monstrous cam (I do plan going pretty big though) to meet my power expectations (about 440rwhp through an M6 of course). I want to do this on a stock 350 bottom end but will be stepping up to a 383 after a while. So I need something that will feed a 350 nicely but a 383 even better. I dont know if I should get some LT1s ported, LT4s ported, AFRs Ported, or even the edelbrocks. What would you say would be the best head for my plans?
