| R - Swoc - Noted Pm Herewith information from AEC on valves & seats. Such an arrangement could be tried on PAIII. Appears as though they would like to Stellite exhaust valves if they could apply it without trouble. Their valve material is identical to our Silichrome which we also tried to Stellite without much success. Pim/SWOL | ||
