You can go as wide as you want/piston allows if you have enough arch.
But the port might not flow any better than a square 60%.
Another thing is the symmetry to the arch, it it is not very symmetrical the ring will rock back/fourth eventually freeing the pin. More so with extremely wide ports 70%+.
I probably use more arch than most, but I haven't Tryed to find out how far I can push before things start hanging...
You're 300' from your Dad. Enjoy it.Shop at dad's house. (300ft from mine) is where the lathes/mills are. All the porting is done in my garage.
Never fails when I'm over doing machiene work, I get roped into doing stuff for dad lol.
I'm a leap of faith from mine. Hurts every single day.
Sorry to drag yall down, carry on....
