Sometimes you should not look

150 psig compression is excellent for a slant. Must have been real gomers to try lifting the engine by the small T-stat housing bolt. The two big tapped holes on the top of the head are for lifting. Good you are checking everything and going slow. I wouldn't have even thought to look for the rod oil-squirter holes. I did a ring job on several engines, but never separated rods from pistons, so must have put them back right since the notch on the piston was facing forward.
