My vote is for the 305 heads and the l98 cam, heads should be 58cc, the l98 are 64cc.

Get a set of LB9 heads. Theyll flow well and you wont loose compression.

aluminum L98 heads are 58 cc, if you are only considering the Z28 L98 heads then go with the LB9 heads.

The L98 corvette heads and then an LT1 cam....that should bring some flow and more power, right?

With lots and lots and lots of tuning. I got that setup and its still far from running right. I believe it has something to do with the intake manifold im going to be swapping back to a stock style manifold see if it clears some issues up... But be prepared to tune, or pay some1 for a chip that wont work. ASK ME HOW I KNOW!
