Has anyone here had there front valve cover and intake manifold polished or chromed? If so how much did it cost? I was polishing them my self but it takes way too long. Also if you have yours painted, how long does the paint look good for? Does it dull after awhile, or turn brownish because of the heat? If polishing or chroming are too expensive I will just paint then both silver and put clear coat over it. Will the 500deg. engine enamal really hold up? thx again.
