    leaning on the polished fins on a black valve cover shows the difference in heat retension / transmission of polished parts vs black painted ones
    If I do one by hand, it'll definitely be a simple rectangle.

    How many people would be interested in some spacers? It looks like pricing would be under $100 each.

    If you started with a water jet cut piece and then add O-ring grooves to both sides via conventional CNC cutting it would probably double the cost easily. Cutting is the easy part, all the setup to get there is where the time/labor gets $$$.

    Hey guys just thought I would remind or inform all you guys with 2 piece manifolds that white OEM gasket (that is seemingly welded onto the manifold) contains asbestos. Lets hope none of you have been sanding that gasket off!

    I wonder if mine had been changed before. I remember when I did the brake booster I removed the upper half and the gasket was brown or black. I know the head has been off at least once before.

    On second thought it must have because it has a TU fuel rail.

    Sounds like you had the Fel-Pro. The Fel-Pro gasket is a black paper gasket that is like 1/3 to 1/2 the thickness of the OEM white gasket. Usually one has lots of trouble trying to pry the two halves apart when using the OEM gasket.

    So 30 years from now I'm gonna regret using a brown scotchbite disc on my die grinder to clean off old gasket? For the past 15 years or so I always put a big fan behind me to blow the dust/chips/carcinogenic particles away from the holes in my face
