On sbc's, depending on headers, it can get pretty tight. I use small head bolts with inset allen key heads...and there are a few that still rub.
What kind of header gaskets? Exhaust port/header port shape?
Just thinkin' out loud here. The oil pressure thing...could the filter bypass be clogged?

Another good idea Jake. Ray Barnes fired up his 396 after a rebuild, bypass was blocked, and he had no oil pressure trying to break in the engine. The filter was clogged with assembly lube. Changed the filter and all was good.
