<<Why wouldn't you want to just weld up the pits and have the head
flycut for proper sealing surface at the barrels.
That JB patch is just half fast way to be doing the job a second time.
An then there is the potential that you heads have reached EOL and
should be replaced.

Stan,
The answer is simple.
The JB weld is $3.95 a package.
How much is the tig welding, and the fly cutting?
Cheap, and halfed assed is the best way to go for filling head corrosion
pits I guess.
JB is OK for a quick fix in a non-essential items.
For this job I too would prefer a welded and cut back to stock mating
surface.
This is the right way in my opinion.
