chrome or ceramic headers

you could also look at it another way other than just for rustproofing. the coating does a dual role 1st it reduses underhood temps which helps to cool the motor compartment and air charge but another gain is that by retaining heat within the headers( the purpase behind header wrap) it increases the exhaust gas velocity. hot gasses expand and travel faster which increases the scavenging effect or exit inertia which cleans out the cylinders more quickly and draws in the next air/fuel mixture more efficiently this gains some more hp and maybe net some better gains with a future h/c/i combo's.
now this is what I have read in various articles but a gain is a gain :rolleyes: .

I'm also planning on the ford racing coated headers myself, I would like jba's if I could spring the xtra coin.
