Cranking compression, one head at a time?
Had a set of steel shim head gaskets fail on a fresh rebuild. Not sure why, but I tore the motor back down to the short block, cleaned everything up and went with 1094 this time (same gasket, just rubber coated).
I want to check things out as I go. Anyone see a concern with installing a head, checking cranking compression, then installing the other and doing the same?
I just don't want to put the whole thing back together only to find a problem again. I'd rather know early.

A good straightedge will tell the tale. IF the heads/block are not flat, any gasket is going to fail eventually.
Steel shim gaskets are usually sprayed with a coat of hi-temp aluminum paint at installation.
