Figuring out how much heads have been cut?

That's the way I always check bbm heads.
No way to know how much the block has been decked while in the car, that I know of.
If the heads were off, and IF you knew the compression height of the pistons, actual deck height could be compared to calculated dh.

Thanks. I wasn't sure if there was a certain feature X distance from the deck surface that could be used as reference. I can check the head at least. The pistons are a good bit further in the hole than they should be for a stock bottom end, so I have no idea what the bottom end is.

Attached is the bottom of a piston, it shows the only identifying mark on it, the other pic shows how far down in the hole it is. Don't mind the carbon on top. Lol
