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...

Typically if the stock 243 clears, ours will as well, but we always recommend checking PTV clearance.

What are the specs on the trak cam? I cant think of any vehicles that we've done here with stage 2 heads and stage 2R cam, but I think it would make slightly more power than the stage 2 / stage 2. | |

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,
Rick LeBlanc

Are the valves stock GM? Are the exhaust valves sodium filled? What are the spring pressures?
Thanks,
George | |
