Just checked gaskets: The new head set is a Fel Pro7782B. The HG has steam holes and they line up with the head. The early valve cover gasket I got from Jim Carter's is a Best Gasket. I could not get overhaul sets for either a 235 or 261 and rear main seals come in those sets. I had to order piecemeal from Carter's and Rock Auto. I want a Best Gasket rubber rear main seal, 2 ea. They don't sell direct.
