Ray,
I'd be real interested in seeing flow numbers from a flathead block. I wonder how hard it would be to rig up.
Question. Unlike an OHV engine, the area around the valves does not change with stroke on a flahead(the valve shrouding is unaffected by the piston). If you did the flow testing with the head on, once you had your baseline could you play with chamber shapes, shifting the head, etc, to increase flow into or out of the cylinder? Guess what I'm asking is could a flow bench be used to fine tune chamber shape?
