kejross, you're no different than thousands of other newbies who purchase a cam for their rebuild without knowing the static compression ratio, much less the dynamic compression ratio of their motor. You need to get some books and do some reading. You have no business trying to put a combination together without some knowledge of what you're doing.
Just a few of the things you need to understand....
Block deck height
Piston deck height
Piston compression height
Static compression ratio (you need to know how to figure this from scratch)
Dynamic compression ratio
Squish (how to arrive at it and what figure to use)
Camshaft (advertised duration, 0.050" tappet lift duration, cam lift, theoretical lift at the valve, intake centerline, exhaust centerline, lobe separation angle, overlap, timing events- intake opens, intake closes, exhaust opens, exhaust closes)
Head gasket bores and thicknesses, when to use what gasket.
Cylinder head intake and exhaust runner volumes. When to use what head.

Knowing this little bit of stuff will allow you to figure out what parts you need to do a certain job in a motor. It won't make you an engine builder, but you'll be a lot closer than you are now.
