That's what's funny, these studs were brand new, installed once. Yes I cranked down on the studs, and torqued them into the block with an allen, and listened for the gurgling out of them as the air popped out. I mean they backed out bad, like 3 threads were holding the stud in, enough to make that cyl lose complete compression.
