Help with Head Gasket selection

It's more curiosity than anything. Trying to learn more as I go. I haven't been this deep in a motor in 35 years, and that was the flat head in my Dad's '36 Ford five window coupe. There is definitely something goofy going on with the crank. Never seen rough turning on the face of counterweights like this but I'm not that surprised considering some of the other work that was done to the car. Unless I find something major, the bottom end is going back together the way it came apart. The only thing I can find "wrong" with the heads is the exhaust valve tips sit about .017" lower than the intakes, but the intakes and ex are consistent to each other.
