Got the head back!
Hot tanked,milled, new stem seals, valves cleaned, valves lapped. Machinist said the guides and stems where within spec and only a few were lightly leaking, so he just lapped them all lightly. $130, not bad. I also now realize where my 3 missing spark plugs went
Got the pipe fitting, which makes it obvious I didnt start the tap straight. It was too large to chuck up in anything I have, so I had to hand start it. The wall is thicker than I anticipated, so it may support 3/8" NPT after all. If it does I may use this and sell the other one.

I made a video for you gheys. Every hose connection is like this. The water here in phoenix is as hard as it comes, so im guessing a PO used tap water.
Is the stupid starter bracket really necessary? These 2 things.
New gaskets, and the head is on.
Another stup PO thing. The coil bracket broke across one of the bolt holes, so they brazed it with brass rod.
I did an equally shitty job of welding a washer on there. (cops one day)
Reroute!
I also took apart all the HLAs and soaked them in sea foam. Quite a bit of "oil solids" came out of a few of them, most of the varnish is gone now as well. I assembled them with some good synthetic.

These are the easiest HLAs ive ever done. Maybe an hour to take them all apart, clean and reaseemble, not incluing soak time. They just pull apart, they have one simple feed hole, its wonderful. I curse the nissan KAs. They use a 846,992 guage wire retainer that you have to use a nice sharp #11 blade to get under, the whole assembly is the size of a pencil eraser. Youre lucky if you dont detroy it getting it off. After a track session it sounded like an angry family of badgers with advanced parkinsons had taken residence in my valve cover. I hope this makes it all better.

Good tip. If I have any issues, Ill do a leak down and go from there. Wish id thought of this before I slapped it on, but I do trust my machinist. Ive been using him for over 10 years and hes always done great work.

Should have cleaned them for realz while you had em out. The reason I cleaned my KAs in my hardbody was because it had a rod knock lmao.

Got a lot done today.
Down pipe clearence! Ive got a soild 3/4" minimum now.
There should be plenty of room for the divocred pipe, but its going to be tricky
I found this while i was resetting the timing belt :(
Also had a helper today

Going to merge back. The plan is to do it a ways down past the clutch area as suggested by corky. Packaging and dp install/removal may necessitate a shorter run though.
I have a nice vibrant bellows flex coupler that'll go in between the dump and the merge so im not fighting 2 rigidly coupled vbands when installing.
