Thermal Barrier Intake Gaskets
I bet it will make a measurable difference on my SuperVic, but we'll see what it does on a stock intake.
I've always painted the bottom of my manifolds white, it's one of those old school things that's said to help. It wont hep with splash oil however, that's what that little metal shield on the bottom of the stock manifold is supposed to help with, the paint is strictly for the heat and reflecting it back away from your intake. Also, if you're going to space out your intake, watch the gap at the front and back between the intake and lifter valley. You could end up raising the intake up too much to seal with RTV.
