Best cylinder heads for low boost
 

I have a six pound blower and all I want is about 350 hp (I'll take more if possible). What heads and intake combo do you think is best? I was thinking of the holley systemax combo since everything is matched. Also about how much cfm of head flow is needed?

You should have 350 N/A with the holley systemax kit.

GT40 irons or GT40p's, E cam, Cobra intake. With 6psi you shouldn't have any problems hitting 350hp with a tune.

Keeps your valves small, that'll keep your fuel economy up unless you are in the boost, allow for good low end, and it'll flow better than stock heads by far up top too.

BTW, the P's are better.

Thanks for the reply 5302! If you think the systemax will make 350n/a that's the one I'm going with. Any one else have any suggestions?

The systemax II kit works exellent with boost. I you do it be ready for some 11sec passes.

11 sec! Holley it is. I figure with 6#'s, 4;10's, 26x 10" slicks, holley systemax II combo it should be a pretty fun car.
