Good point on shape of the porting. I’ve documented the current 34mm porting and noticed the expansion from the inlet to the region of the valve guide. My trial part replicated this geometry with the added dimensions.

A 24mm socket with a few layers of vinyl tape is 33.5mm in diameter. A 27mm socket is just under 36mm OD. So I can insure I get the comparable taper. And next is to makes sure the transition region is similarly smooth and gentle slopes.
