Heads

[Rosco]

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.
