I am currently running the MagnaCharger with headers, corsa exhaust, and the air raid intake system on my 03 now. Your right, it does a great job. It's just that I am trading it in on a 05 next week so I am pulling off all of my goodies and will be installing back on the 05. I just figured while I was going through the install, if anyone knew if the Z06 heads and cam might help even a little more I would consider doing it. An extra 40-50 HP certainaly wouldn't hurt. </div></BLOCKQUOTE>
More HP is a good thing...

Talk to KenP here on the board. He has a Lingenfelter H@.
When we were at Paragon, he mentioned sending his back to Lingenfelter for (as I recall) some upgraded heads that were good for an extra 100HP...
If you've already done the supercharger and exhaust... then yeah... Heads are the next stage for you....
I did a head job on a 5.7L firebird formula back in 95 that got us 63HP on the dyno with no other mods. Truely cheap terror all things considered...
Go for it!
