Red hot headers
I fired my 383 last night, Comp cams mech roller, 1.6 rockers, AFR 195 heads, Holly HP 750 mechanical, Vertex Magneto, Hooker super comps. Anyway even after I got total timing set at 36deg. my center two header pipes were still turning red, though less then when timing was off. My running temp was about 210 deg. Any thoughts/advice?? I still haven't fiddled with the carb except for setting the float level.

Unburned fuel can enter the exhaust system where it finishes its burn. Kinda hot.

I've always seen it in cars that are too rich. The unburned fuel ignites in the exhaust system and practically melts the headers. Interestingly enough, most header companies won't warranty their products on a new engine.

WAY MORE often rich than lean!
