Fabricate thick Header adaptor flange gasket

My 351W SBF World Product Heads have square exhaust ports. My Hedman 88650 headers have oval ports that are too long and overextend the square head exhaust port flange area about 1/16". Since the header oval port is too big the header gaskets fail in short order (make a ticking sound). I am wondering if I can fabricate a header adapter gasket from 1/8" - 1/4" metal plate to properly mate the square head exhaust ports to the oval header ports?
