I recently bought a set of heads that I was told have been ported and where thought to be hennessey heads but he was un sure. But I plan on sending them out anyways to get rebuilt and ported and milled. Before I send them out I need to pick a valve spring to have put on the heads. So right now im looking at 3 cams. My car will be a street car her in cali that will see a 100 shot and have to pass smog.

Here are the cams Crower stage 2 and 3 and a GG comp cam grind that he like to run on street car but is a bit big and Im not sure it will pass the sniffer

Stage 2 - Street/Strip, lope at idle, emphasis on mid to top end power.
INT/EXH - Dur @ .050” Lift: 230°/230° RR: 1.7/1.7 Gross Lift: .558”/.558” LSA: 114°

Stage 3 - Race/Strip, rough idle, ECU mods recommended.
INT/EXH - Dur @ .050” Lift: 238°/238° RR: 1.7/1.7 Gross Lift: .587”/.587” LSA: 114°

GG comp cam
Comp Cams hydraulic roller:
3634 intake lobe / 232 @ .050" / .600" with a 1.7 rocker
3635 exhaust lobe / 236 @ .050" / .605" with a 1.7 rocker
114 lobe separation, and order it with 4 degrees of advance ground into it.

Which cam do you think will work best in my street car


Now on to springs Im not looking to get a spring that requires a whole bunch of machining to get to work and titanium retainers and all that. This is just a buget build looking to make good power. So far I found these pac racing springs that a direct drop in that retain stock retainers. Would these work with the cams above? Thanks for your help and suggestions

Sounds like the cam vipertony has. Reach out for him. My cam isnt quite as aggressive so i cant say for sure. I know tony loves his setup.
