Is the non quench dome deck at 0.0 deck or where is it?
what gaskets are you considering thicknesses?
are your head chambers equal depth at each end? equal cc's each end and centers (you cut for largest and open up the smaller ones till all are equal)

The other version is zero deck at quench head.
Heads .030 deep, all the same. I milled the pistons different amounts to even account for the couple thousandths diff in rod lengths.

They all cranked the same.
Could have been a fractured wall, from the cooling jacket or pin seized. Remember the pin is stuck in the rod and ends broken off. Maybe a spiro lock gave up. Gueses.
