Small block cylinder head specs

what 66 said
if heads are not off run a compression check
if off measure the compression distence- piston top to deck at all four corners and post back
also describe the piston top - dish, 4 valve reliefs etc
if engine is apart measure the center of pin to piston deck
doing the cam and quench can reduce your EGT by 5-600 degrees on a 360 and 800 degrees in a 440
