As for my face...
That is the result of a phenomenon refered to as hose whip.
@muddysub has likely seem a victim of this.
The pump is capable of something like 1800 psi of pressure against the concrete. Well sometimes the pump plugs. 99% of the time it happens in a reducer. The boom pipes are 5 inch I.D. The output hoses vary, depending on numerous factors, but this particular day I had a 3.5" discharge hose on. This requires 2 reducers, a 5 to4, and a 4 to 3.5. Well the pump plugged, and pressured out. And then released. All in a split second. The result was a ten foot long 3.5 inch I.D. hose that whipped around, still full of concrete, like a fire hose. And it hit me in the face hard enough to knock me down faster than I could put my hands out to stop the fall. Face planted in the gravel.

Yikes, glad you're ok!
That had to sting, I've been hit in the face with hot hydraulic fluid while swapping a cylinder at work,but a high pressure concrete filled hose sounds a lot worse
I've seen it a few times. Actually my first experience with concrete pumps was when I was 16, I was a laborer. We had a pump on site doing a second floor deck, the hose whipped and hit guy, broke his leg as he fell.
I guess thats why the oil industry nazis make us have whip checks on everything
I went to the yard again in search of a new exh manifold, but I I could find were cracked ones...
I decided to buy the least cracked of the bunch as insurance and try my hand at removing the broken Y-pipe studs in my old one. As luck would have it, I managed to get them out, no heli-coils required.
Found a bunch of these spark plug wire heat sheilds in the process of looking for manifolds, and found a T-stat housing that wasn't corroded around the hose neck. Also grabbed a plug for the 700R4 so I can wire for lock up until I swap the TBI and associated harness in.

So a buddy at work gave me a set of these factory headers from a late 80's vette, and a y-pipe to run passenger side 3 inch exhaust. All of the extra nonsense for the emissions stuff has already been cut off and welded shut. I think I'm gonna try and make them work.
Edit: I meant to say driver's side exhaust above, NOT PASSENGER SIDE.

You still running AIR injection? Interested to see how those fit.
My rig was non AIR factory, so it is no problem that all of the emissions stuff had been cut off and welded shut already, the above pic is just a pic from google, not my actual set. I hope it works good. The guy I got them from said that they were on his old K5, then in his scout before he swapped a LS into the scout. So hopefully just bolt on and go.

Got back to the yard and talked with my work buddy that hooked me up. He said that he ran these on straight plug heads for about 7 years. The plug wire clearance was a little tight, but he never had an issue. At all. He was adamant that he didn't get exhaust leaks, didn't burn up wires, anything. He said that it was the best combination of functionality and reliability that he ever tried. So I am definitely going to give them a shot.
Plans for this weekend are to swap the vette headers on, fix a couple broken wires and get the engine back in. Then I'll either work on front springs (disassembly, clean, paint, new bushings, reassembly) or get the trans and t-case back in. I haven't decided if I think it will be easier to have jack stands in the way or a front axle in the way while I put the trans back up.
I am leaning that way too. Plus if I get the springs and axle in, I be able to measure angles and get shims if need be while I still have other stuff to put together. Would hate to wait on pinion angle shims if everything else was ready.
