Jason;
First, the part number you quoted is a Comp cams, not a Crane.
Look here.
If you are running headers, that cam should work OK. If you're running stock manifolds, go back to the factory L78 grind.
Crane makes the current favored replacement.
Next, get rid of those .050" head gaskets. Unless the block has been decked, you're going to have roughly .075" quench distance, and contrary to popular belief, that will make the engine
more prone to spark rattle, or "detonation." If the block has been decked, use a .039" gasket such as the
Fel-Pro 8180. If it hasn't been decked, you can use an
OE style .020" steel shim head gasket to keep quench distance in check.
