Re: Better Piston Rings
The old adage:
Slide valves wear in
Piston valves wear out

They were like $7 and they came with a photograph of a completed engine and a letter from Ray thanking me for the purchase and to please send progress pictures. Never built. Still have the packet somewhere. Found his ad...
