well along with superbleeders idea, if you were going to actually do something like that just get a piece of metal machined like a h/g and then run a thin head gasket on each side of it.... so you would have a metal spacer. Now don't get mad at me if it blows up the first time you boost her
I actually wonder if that could work???
after a few moments of thinking, you would need the metal "gasket" to be 100% flush with the cylinders in every way.... so that would be the weak point maybe????
