I have a 55 Club Sedan, 292 C2AE .060 over block, G heads, Fordo transmission, original 55 t barrel carb, 62 Ford passenger car distributor, vacuum advance hooked into the intake manifold, running Autolite 46 plugs. The motor is all fresh, and has about 100 miles. So...I decided to pull a few spark plugs to see how we are burning, though I could not notice any pings, knocks, etc. under hard acceleration. Everything seems fine, and the performance is wonderful.

All of the spark plugs I pulled have a light orange coating all over the ceramic, but otherwise appear ok. Is this coloring normal? I don't remember ever seeing the plugs this color.

I am using 93 octane fuel.
