Since you mention it...  Is there any reliable way to weld up or otherwise
repair cracked HS headers?  I have an original 1996 vintage set.  Besides
the standard 1-4 crack, there's one along the bend of the #4 tube, right
out of the head flange.

I ground the ceramic off.  And drilled some small holes at the ends of the
cracks to stop them from running further.  Can any old welder fix 'em
up?  Or do I need someone with skill & a TIG?

I've heard of using an acetylene torch to burn off deposits.  I don't think
an oven would get hot enough to do much good.
