GOOD NEWS first.
The weather came out of the Artic Sub Zeros! Started Jeep Soup.

Jeep Soup is running like a Sewing Machine. Really quiet, and NO lifter noise. STARTED Easily, with minor Carb Adjustments. !!

Well, SUMS a BISCUITS !!!!

I "Disturbed" 2 head bolt nuts to remove the Air Cleaner Tube crossing over the engine to remove the Manifold.

I have a weeping antifreeze leak at the head gasket by these two head bolts. Cranked them down to No Reprieve !!

Oh Happy Happy Joy Joy, I get to replace a Head Gasket.
 
Solution
Now in my own Defense......
Here is what I found causing the Antifreeze Leak.
A bad CHEAP Head Gasket was use by a PO
You get what you paid for !

It rusted through at a Water Jacket Port, and then creeped through the layers of the Head Gasket.

I could not find any markings on the old head gasket for a manufacturer.
I ordered a MADE IN USA "Copper" Head Gasket. Yes it was double the price of a "Best Made in China" composite gasket "Copy".

It is to be here by the 19th of February.

So I am cleaning everything up.
Soaking the head to get the carbon cleaned off, chasing ALL the head studs and bolts threads.
And going to Helicoil repair two Stud Holes in the Block as when I removed the Studs, some of the Threads came out...
On removing the head on a Flathead L134 "Go Devil" that has been on there before the beginning of Income Taxes !!! was a little bit of Patience and Compound Cussing. It separated at the Head Gasket fairly easy,
BUT, I don't know where that Black Carbon Gunk comes from on Head Bolts/Studs on something that is to be a Sealed Fasteners !!
Lots of Liquid Wrench penetrant,
Wiggling, Wobbling, Duck Taped Multiple Pry Bars, Blocks of cut wood and IT finally gave up her prize possessed Head !

Here's the Dirty Look after removal.

And this head must have been "Shaved" in it's past. The intake valve is leaving the mark in the carbon on the head.

This is my Go To Product for Non Solvent Tank cleaning. It actually works better on softening carbon. I mixed it a little longer for this application. Been using this Stuff since the Late 70's.
Excellent engine/frame/firewall Degreaser that doesn't kill your
Lawn or Dissolve your Driveway when washed off.

After about a hour soaking most of the carbon came off with just a putty knife.
I let it soak overnight and will hit it with the Wire Wheel Cup in the Drill today.

Maybe 85 years ago they didn’t need to name their gasket. :wtf:

Blaahaha.....
I did Government Work......
I don't sign anything!!

Well we know it is NOT a original part. Back then, everything had a manufacturing stamp, parts number, and if Army Surplus, would even have a Gov. Contract Number on it.
These ancient parts that even have a casting number on them has saved me hours of searching for new parts replacements.
Once you have a part number or manufacturer, you are Golden to find parts.
 
Yeah I was a subcontractor for the gov for almost 4 decades. Back in the early days of when computers showed up, they even numbered the mouse for the keyboard. Keeping track of government property was a big thing. Now they just hope to keep track of a laptop from disappearing into the abyss
