Well if you going to have the motor apart anyway......

Replace the factory flat tops with forged dished, then instead of getting the FR heads get 99+ PI heads(I think they flow the same), and instead of a FR intake get a Bullit intake(same thing as FR, just made for 99+ heads). This will give you more money towards a blower

Also have the heads and intake ported too

If your gonna get headers and your looking to make maximum horse power, get a set of longs tubes. They are way better than shorties.

From what I've heard the aluminum drive-shaft is worth the money. As for the aluminum flywheel, your car is pretty heavy, a aluminum flywheel is gonna make it a good bit harder to get that sucker moving off the line. I'd stick with the stock one.
