Paul,
I don't know what to tell ya on the engine bay paint, but I thought
all the TR's just used body color.
On the exhaust manifold issue, cast assemblies can be very hard to
weld. The problem is that the crack will want to keep on growing in
front of the weld as the heat is being applied. I cracked a manifold
once, and the repair involved completely grinding out the crack, then
heating the entire manifold to just below red-hot before TIG welding.
The ground out area was then filled in with new metal, and I was given
no garuantees. It did work fine, however.
I can't give you any idea of cost since I shmoozed a neighbor into
doing it for me. He was a professional fabricator for the aerospace
industry before he retired to restore Indian Motorcyles. I told him
the manifold was from a Triumph, and he kept trying to figure out
which year Bonneville took that funky looking thing...

I apologize if this is a re-post. I have posted twice to this news
group and have not seen a reply. Either I'm doing something wrong or I
guess nobody has a response:) So hopefully somebody will respond with
at least a note that this post did in fact reach the masses.
1) I've sandblasted the engine bay and would like to paint it.
What should I use?
2) My exhaust manifold has a 2 in crack in it. Has anybody had any
success with a welded manifold?

I just had my headers welded. It had a fairly large crack where the pipes
join (4-1). I can still hear a slight leak and I don't expect it to last
for more than a few months - but it did only cost me about $35.
I removed it myself, had a local muffler shop do the welding on the crack
($15), reinstalled it myself with some muffler tape for the joint, and then
drove back to the shop for them to weld up the joint ($20). Worst part was
lying under the car for an hour cutting the pipe in the first place.
I think the welding on the crack might have been more successful if the guy
hadn't 'done me a favour' and dunked the manifold in cold water to 'cool it
off' directly after finishing the welding.
Related question for the list - had anyone successfully installed some sort
of bolted flange connection between the manifold and exhaust system? When I
next replace the system I'd like to be able to remove and reinstall it
without welding. The local muffler shop said they didn't think there was
room for a flange without causing a clearance problem.
Regarding the paint, can't speak from experience but I've heard others
recommend POR15 (www.por15.com) for this application.
