To update a previous post: I got my brass nuts off my manifold bolts with our rounding or ruining any. I took a cap off a spray paint can and filled the outside ring
with PB Blaster. I stuck the studs head down in it and left it set a few days. The PB made the brass look semi-new again. I also found it probably wasn't necessary.
As someone said in a previous post, the brass nuts were so they wouldn't weld to the studs. The reason the studs turn out is because corrosion at the end of the studs
keeps the nut from backing out. I found they would turn in easy enough so I turned in, oiled, turn out, turn in, oil etc. Most everybody who has done way more engine
work than me probably knows this, but I post for the few who don't.
