ou seem to have another issue being a vacuum leak. Gonna have to be a HUGE leak to turn 8 headers red, not just a random cylinder or two. Think about it...The headers being red is 99% of the time from fuel being burned in the header rather than the chamber, they dont get that hot from a LACK of fuel

I AGREE COMPLETELY WITH THIS STATEMENT. ID BE THE CAM IS INSTALLED RETARDED AND THE CHARGE IS BURNING IN THE HEADER, NOT THE CHAMBER. I ADVANCED MY CAM AND THAT SOLVED MY PROBLEM.
