You did say that you have already installed this camshaft http://www.compcams.com/Cam_Specs/Ca...x?csid=94&sb=2 Now it is a Step up from the 1981 L-46 Corvette Camshaft . But You could have gone with a Larger Grind . The Head's that You Listed are Good Heads but at 195cc Intake Runners on Your L/C Engine with that Camshaft they are Over Kill . From How I am Reading this Post you have the Stock intake . So you will most Likely be Up-Grading to a Better Performance Intake . With that Said this engine as is would work Well with a Stock Set of Vortec Head's and a Non-Air Gap RPM Vortec Intake . On the Corvette's Hood Clearance would be an Issue with Air Gap Higher intake . Tuned Right with the Vortec's . That Engine should pull about 320 H.P that Camshaft is hold back more H.P Numbers . But it will have Lot's of Low End Torque

I agree that I picked TOO small of a cam, as most guys pick TOO large of a cam. I did install this cam, but am able to buy another, as I am not happy with it.. The reason I picked the heads is that I was hoping going from 76 cc chambers to 62 would raise my compression enough to make it doable to use a bigger cam..Once I have the engine out, I could always install some flat top pistons I guess. That along with a bigger cam I would hope to produce some more power.. Would you suggest the Vortec heads over the heads I had picked?
