Header turned gold on first startup

Hey all, just cranked the 440 for the first time and everything went GREAT!! Except for the passenger header turning slightly gold. Schumacher ceramic coated headers.Roller cam so had it idling and slight revs here and there for 17 minutes. At 11 degrees initial and 36 total. Never got above 190 degrees temp. Oil pressure 40-50.

I’ve honestly never tuned a carb before. Brand new out the box Quick Fuel slayer 750.

Bout to go break the rings in and don’t wanna cook the coating off the headers.

Am I running lean? Wouldn’t it be both side headers turning gold then?
