12.5 TRW 340 Pistons

R u sure those arn't the 10.5 pistons? Do they have 5/16ths ring grooves? What is the compression distance from the top of the pin to the piston top? I may have a use for them. Can u post a few better pics of them. Thanks. Kim.
Info I posted is from googling the L2322 number stamped on top.
They do have less of a dome than I would expect for that CR, so they may have been milled at some point
