Cometic and Edelbrock seem to fit 11/32 valve stems best. I tried to put Comp 510 seals on a .500 head to sell and every one broke on 11/32 Ferra stems. My N heads have .530 seats and 11/32 Manley valves. The Cometic seals are metal shells and the Edelbrock are rubber with a steel band. All positive stop.
