Here it is in a cylinder as you would check deck height.

This necessarily the best way to measure deck height, but for most stock type rebuilds it will work fine.

This measurement * pi * cylinder diameter + head cc + piston pocket/dome volume will let you calculate compression ratio.

More deck height equals lower compression (fuel/air isn't compressed into such a small space). Less deck height equals higher compression.

The more your heads have been flycut (which removes material and reduces combustion chamber volume) the more deck height you'll need in order to compensate to keep the CR to 8.5:1 for stock FI.
