[QUOTE="SlowSVT, post: 12642501, member: 20202"] Powder coating is a pretty straight forward process; I don't think it will make much difference who you take it to. As a design engineer when choosing a finish for hot engine components powder coating is not the first thing that comes to mind. Nothing wrong with it and your engine won't overheat because of it but keep in mind your covering a lot of the engine surface with a fairly thick polymer coating. About 30% if the heat produced by an engine is radiated directly off the surfaces and on this engine that is mainly aluminum which moves heat like a freight train. Powder coating will impeded that process to a fair degree. In a high output FI engine heat is something you want to get rid of at all cost. I stripped the factory powder coating off my valve covers and am leaving the all exposed aluminum bare. The funny thing is after I stripped the powder coat off I could hardly tell the difference. [ATTACH=full]417853[/ATTACH] Oxides that form turn the surface that nice dull gray and prevents further corrosion while providing maximum heat transfer. If it stains a couple of swipes with scotch brite cleans it up and in no time at all it blends in to the surrounding metal like it never happened. Besides, I like the Factory Worx look engine appearance that is "all business" :rockon: Powder coating does look great and is tough as nails. A textured finish will provide the better surface than a gloss one but it traps dirt and is harder to clean. Black will dissipate heat better than a lighter color and hides any dirt that gets imbedded in there. Just something to consider :burnout: [/QUOTE]
