True, but it's maybe a CC or 3 so.

It's just a rough calculator. Some manufacturers not only provide the compressed thickness, they also provide CCs, and you can pump that into the calc under the head volume to make up for it.

this^^^thats what i was getting around to....say for example....1016 head gasket .039 thick 9.4cc volume with 72 cc heads. would u enter it in the calculator as

4.15 bore
3.75 stroke
81.4 cc combustion ' 72cc head + 9.4 cc '
+8 cc dish
.039 deck
8 cylinders
