I have a custom Ross Piston made to my specifications Fits 801 head This does have a part # I can order for you Something I did for a 801 head Angle cut the exhaust ports 1/2” - I do have a set of used pistons mhl11x@aol.com

Found a company that will make me a spur cut gear set. A set to borrow would make it easier to make. I thought I could possibly have more than one set made. Don't know the cost yet. Anybody interested ?
