273 commando Build
I'd bet that deck is most of the issue. This one looked flat with a straight edge also. This is a "touch off" pass with my CBN surfacer. See the grooves? That's the factory surfacer marks, and its shitty. Your block is 60 some years old, should have been surfaced during the build.
