This is a .120" thickness gasket that I tried out today. It does a world of good for my alignment issues! Unfortunately the port openings are rather large for a little 283.
Does anyone know a manufacturer (hopefully with part number) that makes gaskets .120" thick with port openings in the 1 7/8" to 2" range? I can use these if I have to, but I'd rather find something that is a little closer to the actual port size. So far my search has come up empty.
