OK. Here's an update. I'm gonna share the whole experience.  Gonna regret
it later. Motor is making bad noises.

That being said, I'm not at solution stage yet. But I'm having fun getting
there.

So I said I had a bad noise.

Since then I've found a few issues (sheepishly...)

I thought i needed to add fluif to the transmission and had the hose blow
into the transmission.  Got past that.

I then saw that one of the manifold to headpipe nuts had backed off.  Took
care of that.

I pulled the Rocker assy and it seemed OK. Compression check was good
(155,162,167,165).

I then found the belt seemed loose. On the way to tighten it, i pondered
why it would be loose and shortly saw the water pump nut had sheared
off.... and also destroyed the water pump pulley.... I greased up the old
tr2 pump (love the grease fitting) and put it on (surprised at how freely
it turns).  I  The pulley is messed up and I'll need to go to my stash and
pull one. I've put the messed up one on it on there in the meantime.

So why did the rocker arm stud shear off? I went back to the rocker shaft
and it seemed in good shape and no noticible play. I did see one push rod
at number 4 that appeared to wobble when I rotated it.

That's when I really screwed up. I pulled the push rod and could tell the
lifter was stuck to it. I shook and wiggled and felt it had dropped back
into it's hole. Nope. It decided to lay sideways.... there is alot of room
for unrestrained lifters to flop about in a tractor engine.  Took an hour
and three beers to get it back in the hole. (Not going there ) buttoned
back up and the noise is still there.

I then pulled the head and all looks good.  Now i'm kicking myself for not
taking the belt off to eliminate the water pump and alternator first.....
