just picked up the tin at the powdercoaters.
we did a textured silver finish. wanted it to look like cast aluminum, came out pretty nice.
the valve covers didn't come out as nice though. the inside is bare blasted metal not super smooth like the original finish. not sure we will use them.
i cut the main tins pretty high but you can see how the smaller air guides fit up into the main shroud. should work ok, I'll let you know.
