This guy had a little problem, a rock put a hole in the radiator, engine got hot spot in head and grabbed two valves and piston made them into art. The others appear to be find, they cleaned up on regrind. Intake is 11/32" X 5.000" X 2.125, exhaust is 11/32" X 5.080" X 1.600". These can be used in an engine or for another set that's not complete or for mock up. If you want an intake and exhaust to match these I can order new. Just didn't want to throw them away if someone can use them.
