Hotrod Lincoln Did you ever see a tool to cut the top ring groove to install a steel spacer below the first ring?? Had one of those in72 it worked fine was Hastings I think. It liked to have it's cutter flat honed each cut because aluminum would build up on it. By chance still have the tool,if I could find the spacers.It would make the groove fit good with a steel sealing surface below,looked like an oil rail ,had to understand to stop at the groove bottom then hone it for the next cut.
