You could do some Kooks 1 7/8" headers and high flow cats and get another 40rwhp. Start saving for a new forged motor..

replacing heads ?
what would be a good set of heads to get for my supercharged car ?
i got the p1sc on a stock 98 motor. I was looking at some z06 heads, but not sure if they would bolt up? thanks

Z06 heads should bolt up fine, with the exception that apparently newer heads (late 2003 and 2004) seem to have a different bolt pattern/bolt length configuration? I don't know for sure, I've never seen it. It just came up in a reply from a recent topic I posted.

do you know the casting number for the z06 ? i would liek to have some 918's installed then swap them out for my stockers!! I think it would be a good set up for what i have. Should i worry about what compression i have also , im not real sure where i sit now with what i have !!

Any heads will work on the block.. the bolt pattern is the same, it is the block that cares.. NOT the heads.
As mentioned 243 heads... again, I think your $600 is better placed on a start for a built bottom end.

If you are FI, I'd go with the 317 casting 6.0 L heads. They flow the same as 243's, but have 72cc chambers for lower compression.
FWIW, I installed a set of Z06 243s and on the dyno I didn't pick up 'any' HP. YMMV, as every engine combo is a bit different.
