Getting the valve job done, I wouldn't replace the stock cam with another stock cam.

On specs I like the crower 267HDP... INITIALLY suggested the 271 at FBBO ( although gave the 267 option later ), but is true, it could be a bit big with stock CR, unless you bump out the CR cutting heads and using metallic headgaskets..

Although I WOULD STILL cut the heads ( light 0.020" cut or so ) and use metallic headgasket with any cam you choose.
