Just bought a short block and i am now the owner of someone’s brain child cylinders haha.
I have never seen anything quite like it so maybe someone can educate me?
im assuming the idea behind it was to extrapolate the most power on the top end with the PV’s wide open.. but the power valves don’t even clear the exhaust port entirely when pressed open
Looks like a great way to snag a ring to me but maybe it’s some super secret old school porting job that I’m just to young and dumb to grasp
Thoughts?

pics of ring snag damage on roof of exhaust port due to minimal chamfering and huge port..
fit piston into cyl and can compress the rings considerably when they’re lined up with the top of the port.
also, check out this radius LOL
