SM Head Modifications on a budget
Clay has nothing to do with ridges in the chamber. The 15 degree cutter that was used for deshrouding up to the gasket line is shown in the picture. It leaves a sharp inside corner and a vertical wall, both of which I believe are bad. With clay I can fill in the sharp inside corner, test on the flow bench before I go to the trouble of making a custom carbide cutter on the knife grinder.
I want to play with valve angles and top cut angles because it is fairly easy to make these custom cutters. Just a whole lot easier to start with clay.
