The pictures look good. I concentrate on three areas in the intake port, the
throat size, the push rod pinch and the width of the apex of the short turn.
Thats the only areas I remove much material.

I'm not concerned with low lift flow, the piston is still near TDC at that point.
The mid to high lift curve is more important IMO. If running a near stock
engine at low RPM low lift flow becomes more important.

On the exhaust side I resize and shape the entire port past the throat. I'll take
pictures when it warms up, no heat in the shop.
