The return leg of a quick trip to Yellowstone found the '63 with a distinct lack of power and a truly nasty exhaust note. Compression? Cyl 1:zero, 2:192lb, 3:zero, 4:180lb.The head came off to find two burned exhaust valves and wads of carbon build-up. Too lean a mixture probably though DAILY checks of sparkplug color showed the desired soft serve chocolate color.
What should I ask of Autosport when I take the head to them? Hardened valve seats of course but what else?
998, 20 thou overbored (now I know), Maniflow exhaust, Howley intake with single HS4.
