Looks good. What other mods do you have? Should be solid 550rwhp car or more with a decent header/intake setup.

I will get an intake setup, but leaving headers stock. I had an issue with drone with my base c6 and like the original exhaust.
I love the fact that I will get extra horses, but I am primarily doing this to have a peace of mind and no surprises. I plan on some long trips in the spring/summer.

you will need to change out the springs on the heads. that cam on a 1.8 rocker will be around .650 to .660 lift. the heavier valves plus the higher lift of the 1.8 rocker with that cam and you will find trouble at some point.

prc has a set good for .700 lift as well as comp. I am running the comps on mine. they are not cheap but it will save you a lot in the long run.

PRC has .675 springs for a few bucks more. Just get those if you are worried. Texas Speed said the .650s would be fine for .650-.660 lift when I talked to them.
