They are a domed top piston, you can see in one of the pictures the illustration on the instruction manuals. Probably a very close if not the same piston to the increased hp factory pistons. I have a set of the Higher HP pistons out, they have a pretty big dome on them. :D

AP137 pistons are flat top pistons, and other than the fact that they were marketed by M&W, there is nothing special at all about the set. The M&W specs list 0.040 pistons (ap137) as increasing the HP of a cub 1/2HP.... This increase would be the same with any other 0.040 piston. On a side note, M&W offered the largest overbore piston that I know of, a 0.062 Oversize (AP136), and also offered these pistons with repair sleeves (SP136).
