G'day if you want to make a gasket to try it out use exhaust manifold gasket material the one that is like a heavy paper compound not the steel one you should be able to buy it at a good auto spare parts place i have done this as a get out of strife fix and have had it last for nearly twelve months (had the new gasket in shed for eleven months just never seem to find the time
) but this will work to try it out, also i would cut the cut out back to 120 psi won't notice any difference in performance but less stress on compressor. Good luck with it all
