My 428 and new heads. I think I'll make better power and pump gas friendly.

Is that paint or some kind of coating on the chambers?

I had 2.90- 1.75 valves, unshrouding and a bit of clean up in the bowl. I also had the springs changed as the Edelbrock singles had varied seat and open pressures. I can only assume it is a machinist dye.
I have always seen blue, never red in the past.
