ICON 9976 with Magnum Heads?

Doing a google search, I just found the UEM Facebook page and it lists 3.58” stroke for this 9976 piston, so that should be fine and does match the intended compression height.
Looks like a nice piston. Formed head relief instead of machined, to lower cost, but otherwise very similar to the IC741 that has machined valve reliefs and top.
