I think I pretty well understand the options for exhaust manifolds, so I would like some advise for the intake manifold options. I want to protect the paint on the intake manifold as much as possible. If I have it correct, there are two ways to do this.

1. Purchase the 292 HD truck manifolds that come with a thin piece of sheet metal installed on both sides (29 gage steel with 1/2" hole)  which reduces the heat passing thru the manifold under the carberator. The metal is 1 9/16" x 1 3/4" with round corners and confirms to the shape of the gasket.

2. Use the stock gaskets  and fabricate your own thin pieces of thin sheet metal on both sides and use a high temp adhesive to hole them in place. This option would be using two pieces of 29 guage sheet metal on each side of each gasket, 1 9/16" by 1 3/4" with no hole (or hole of your choice) in the middle. You would then gule one fabricated sheet metal gasket to each side of your stock manifold gasket before installing gasket to head.

Do you use a sealant on intake manifold gaskets?

If you do not want to "block off" the intake port and need the port option to heat a choke tube, can the intake manifold be installed with a sealant and no gaskets?

I would like to hear from the members before I install my manifold.
