Head is a 20R. When I tell you it is, don't argue, just nod your head and agree with me.
But alas, all is fine with fuel pump. I put original thermostat housing back on intake manfold and managed to get the carb fuel inlet to clear.
Still think I'll pick up a fuel pressure regulator, but aside from that, I should be good to go.
Thanks for you're advice and input!
