Might be a small market for someone that wanted to get crafty at home in the garage, With a couple of patterns I would start with a chunk of hard wood, trace the pattern and relief out with a bur head or drimmel tool then shape some plates and hammer them for a depression to hold them in place. SB ones are fairly thin metal so that they don't get in the way of the posts sealing (too thick of sheet metal)Thanks for the input. I am leaning towards a .030 piece of stainless in the gasket cut out for the heat riser port just enough oversize to keep from falling in and silicone the plate in with the gasket . At least until I hear a better procedure.
Just a thought about a possibility
That's pretty much exactly what I did with mine. I used Permatex Ultra copper gasket sealer to hold them in place. That was back in 2012 and to this day the paint still hasn't come off the intake manifold so I assume they're working pretty well.
