Rule x.x.x. Hand Tools Mods / Tech interpretation and enforcement is that any work done to an engine with a grinder, Dremel or file is open and no points. Examples include gasket matching intake and exhaust ports, deburring intake runners or knife edging throttle body blades. This does not allow CNC porting or extrude honing.
