Header shine
I installed some flow tech ceramic coded headers on my 383 stroker after the engine was installed. I put about 400 miles on them with breaking in my new engine. I know they say you should not do that when breaking in a engine. Then i decided to go with a efi system and then the shine turned into a dark grey color with in 40 miles. Any ideas what can lead too this?

Have you asked FlowTech? Five hundred miles of conservative driving is normal for engine break-in, followed by an oil change.
