.060 small block 400
6cc flat top pistons
zero decked block
.051 head gasket thickness
62cc combustion chambers
2.02/1.6 valves

Is it possible to tell with numbers or does it NEED to be checked cause every combo is different?

yes not to be hard on you do not build engines then you will not have to check any thing .even the small bit that you put on here is not telling much if a race piston like JE etc they will some times put a deeper valve fly cut in .i still have cut them when all thing s should of work. it need checking a hi lift roller cam with a wide lsa and small dur cam cam help
