Then the indication of a bent rod -

I eyeballed protrusion between pistons 1 and 2. On the intake side there's about the same amount of protrusion. On the exhaust side piston 2 has about as much protrusion as on the intake side whereas piston 1 is about flush with the deck. That suggests that piston 1 is rolled about the wrist pin axis. But the piston is free to roll. Why would it assume the stance because the rod is bent like a letter C?

I'm kicking myself for not doing a compression test before pulling the head.
