The best thing I can say is (part of the reason I use them) The livernois heads use a 243 casting, and stock ls2 valve. So 99.9% of the time if the stock 243 clears, the livernois one will clear as well...

Thank you for verifying that Brian! You are correct, the MI Residents only applies to sales tax.
Typically we see about 100 RWHP gain from Stage 2 Heads, our Stage 2 Cam, Kooks Longtube Headers & X-Pipe w/ Cats, and CAI.
Please see the graph below from a 2005 C6 6-Speed
Andy is also correct. Typically if the stock 243 clears, ours will as well, but we always recommend checking PTV clearance.
Thank you

Good heads. I think I paid $1200 for mine, so this is a really good deal.
As far as hp gains, I did Livernois Stage 2's, TR 224/224, LT's, and cai at the same time and picked up 102 hp on an LS1.

Brads01WS6,
The stage 2 cam has excellent drivability. Please view the following link for a video clip of this camshaft at start-up and idle.
Stage 2 Cam - Start-up and Idle
If you buy the C5 Performance Package, I will work on pricing for you.
Thank you,
