Painting the Plenum

The valve cover was leaking oil (cork gasket), so I thought I would replace the gasket. While I was doing that I thought, why not paint the valve covers with VHT flat aluminum paint. And since I needed to remove the plenum to get to the valve covers, paint the plenum with VHD red fire paint. I then started removing stuff and preparing it for painting by cleaning. The black tar stuff inside the plenum is the worse. How clean does it have to be? Do I need to take it to a machine shop to be cleaned? It there a product I can use to clean it myself? Thanks for the advice.

inside the intake i would not worry about.

Sounds like a nice project but next will be the a/c ,alt and p/s brackets to finish it off. lol when done you should post some photos before and after

A couple of cans of carb cleaner will dislodge a lot of that carbon buildup. Get as much of the gunk out before spraying to be more effective. Every so often run half a can of Seafoam into the intake via the brake booster hose.

BG44k and GM's Top End cleaner are good calls. That gunk isn't good.
