Another thing to note is that the cut angles are only a starting point, I vary the widths & blending of the cuts by hand at different points around the seat, the finished angles & widths are very different on the long & short turns as well as the bowl sides, so simply stating the angles & widths that I cut on the machine doesn't really describe the angles & widths on the finished head (if that makes sense), they are simply a starting point.
For what it's worth:
Intake
80 deg throating/blending cut to 85% of valve size, 60 deg bottom cut, 45 deg seat, 32 deg top cut, 15 deg chamber cut, radius into the chamber wall.
Exhaust
Full radius into the throat, 80 deg blending cut to 87% of valve size, 45 deg seat, 35 deg top cut, 15 deg chamber cut, radius into chamber wall.
cool info... give thanks bro
