That was the plan. I want to use a PWK/KOSO style 34mm flat slide carb with this head. The trick will be reshaping the ports without killing velocity off, which is where the tapering of the port "bore" from the opening down to the valve is crucial. I want to improve flow without killing charge velocity so it maintains a good swirl and atomization at low engine speeds.

One thing this head does have going for it is the limited amount of short side radius bending and valve shrouding. The angle of the valves is fairly wide, so it does have that going for it.
