wanted to know if anyone could give me a ball park idea of how much clearance i would have with my combination. i the cam i'd like to put in it is .630 lift minus lash, so about .610 or so net lift, but don't want to buy the cam and clay everything if i don't need to. just thought if anyone has had a similar combo it'd save me the time....plus my block is still getting machined. i have....

.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?
