Sorry, I didn't run the measurements. Stock 4-valve relief pistons that came flush with the top of the cylinder.
I should have mentioned that this was a short block-up rebuild and was the result of leaking head gaskets. The PO had said it was low miles on a rebuild which at first was hard to believe given the mess he had made using barrs leaks and what seemed to be tap water damage. But once I had the block out the bores measured/looked really good and still had crosshatching so I decided since it didn't smoke before I would drive it for another couple years (hopefully).
