Well I bought all 4 valves and were able to lap them in and get a nice even grind around the surfaces of the head and the valves. Still not sure how a steel valves wears but the seats are still fine. Any way got it back together yesterday and it fired right up. Wouldn't even start before I tore it down for the adjustment. Now it fires right up.
