Re: what is three-angle valve grind? (kickster)
The portion of the valve that contacts the cylinder head...where it contacts the head, the edge of the valve face is cut at 3 different angles, ensuring a better seal between the valve and the head.
Check out the Bentley, Section #3 (engine), page #29, at the top...it has a couple of drawings of a valve face. You can see how at the face, it is cut at 3 different angles..it just provides a more reliable seal for the valve face.
That is about all I know about it really, and that I have a 3 angle job on my valves, from when had the head rebuilt
