OK, so today was exhaust passenger side, needed to be done to put o2 sensor bung in.
Used the factory style separate gaskets, no sealant. Thought I might have a match issues since I have Vortec heads, but using gaskets as a guide, they matched up perfect, forgot my torque wrench, so I'll do it tomorrow when I do the drivers side.
Did run into one issue, of course, the placement of the trans temp. fitting is close to the exhaust pipe, need to relocate, drop pan and find a better location

found out why they put that bend in the frame fifty years ago... so I could use my march electric water pump mid alternater mount and swing it to get enough tension on the belt.lol
