From the factory there was no exhaust gasket, only an intake gasket. The exhaust bolted against the head tight enough not to leak, (8 exhaust bolts vs 4 intake bolts), although most of the aftermarket gaskets I used had an exhaust gasket stapled to the intake gasket. The '71 2bbl cam is supposed to be the "hottest" cam Chevy put in a Vega. According to GM, there was no difference in the grind, but the '71 had a different part number. I used one in the Vega I autocrossed. I have chronic "Brain Flatulence" myself!
