Exhaust valve color
I removed my headers and found that my exhaust valves were this color. The motor is fed through a Demon 850, Edelbrock Performer RPM, a street strip high revving cam and burns 100 Octane Sunoco fuel. (due to the high compression.)
Is this color normal?
I am also replacing the timing chain and harmonic balancer. Since the engine sees 6500 RPM, what are the recommendations for both?
