Hi there, I have a set of four flat top pistons sitting in front of me, they are still in the box. The thing is three are deffiantly flat tops. One of them has had some machining done to the top and has the following numbers stamped on the tps aswell   RA2656Y   1.50 BOT 0.05 HA   What does this meen??   these pistons have STD bore 85.00 use ring set PS1149-1.50 Piston assembly kit suits 4 cylinder. They are RePower brand made by ACL pistons   Can any one help me identify what these are for, and why only one has been machined? Thanks.
