Heads

Rosco · 03-16-2002, 02:07 AM

Well I've been talking with a bunch of people in the past couple days and I have a couple questions about heads. First off, is there much of a difference between Iron and Aluminum heads? (other then the weight difference?) Also, I will be putting BBK Full Length headers on my car with the shorty offroad H-pipe along with the flowmaster Force II (2.5" exhaust) I was then thinkin of putting a new cam in (possibly the B303 or E303..although i think the E303 would have a little to much lift and drain me a bit) and A Edelbrock Performer Intake on....I've been told that I should also put heads on as well. I've seen kits including heads and the intake and the cam, for around $2300.. My question is, what kind of heads should I go with If i decide not to buy the kit? Also would i need others things like bigger injectors, bigger fuel pump, etc.

I just put a performer intake and AFR 165 heads on my car and they make tons of power. Haven't had it on the dyno yet so I can't give you any numbers. I have seen similar combos to mine make over 300 rwhp. There are cams out there that make lots more power than an alphabet cam. My compition cam has .544 lift and a lot more aggressive lobes than the e cam.
