Ported heads and Stage 3 cams

[TNTLightning]

Just recently scored some stage 3 ported 03-04 cobra heads complete with comp stage 3 cams/springs/locks/retainers and secondary chains already installed. Some of you guys with ported heads and/or stage 3 comp cams post up and tell me what kind of gains i will be looking at. Maybe this will motivate me to install them. I have full bolt ons, KB 2.8H, Kooks long tubes, Jlt, fuel system, killer chiller, etc, etc., etc. I'm looking at 18-20psi pump gas tune and 25psi race tune. Just looking for some possible numbers. Currently im at 623rwhp. Thanks guys.

Really? Nobody has ported heads with comp stage 3 blower cams?

I want to do that! you can give them to me and i'll install them and tell you how they dyno.

at the same 18psi i would say you would gain around 40-50 hp... would be ~ 675hp. 25psi... not exactly sure but maybe be around 725-750.

Depends on the port job. If they are done correctly from a well know shop you could easily see 100hp plus gains with the cams on your race tune. At 18 psi maybe 50-75.

I'd want to bring the compression higher to take full advantage of the heads and cams.
