The Net said both ways, of course... but the penetrating oil is on my "town
list" so I snugged em up carefully, cold, first...a couple aren't moving,
but the noise is gone now... I'll get some p-oil and baste the parts, then
snug some more, I guess "cold"...and careful...since two are already broken
and in need of drilling out ...grin. and I have no drills or taps with
me... Thanks

Were it me, I'd run the engine a little to heat up the manifold etc., apply
some good penetrating fluid, (Kroil?) repeat, then try removing the
fastener. Safety first of course. (Though I have yet to see that type of
fluid ignite on a par I've heated up with a propane or MAPP torch.)

The good news is that I'm pretty sure the stud metal is fairly soft. At
least the exhaust manifold stud metal at head is. I realize you at out in
the wild though.
