ok, the scoring might be worse than I thought, it's about a 1/2" wide by 1.5" strip of scoring going from 1/4" below the exhaust port to the top of the cylinder (like it's following the ring)and it's from the middle of the exhaust port to just past the edge... I'll clean it up and if if doesn't run, I'll chock it up as porting practice... not to mention the ring gap is .015", if the thing actually runs, I'll get a bowman ring for it
