sorry must have confused it with another thread that jb welded the bbi fittings.
now I am more confused.
curious of Kevin's replacement fittings.

That thread shows a picture of six fittings, and the oil cooler looks like it stayed on the motor. Did the two oil cooler fittings get welded also, bringing the total addressed to 8?

1. Remove stock fittings, knurl, JB weld and done.
2. Buy fittings (thicker walled for welding, though you can use OE) from ebay from Torque Solutions for $ 150 and have them welded (IMO the best way).
-or-
Some just drill and tap what's there which is the pinning method, essentially locking the fitting into place with the water manifold as the "pin" is a small allen bolt going through the housing and fitting making it locked together mechanically.

I know we could go in circles on this topic forever, but I still don't understand how welding is any better than pinning.

My understanding is that pinning could still leak if the sealant is compromised, but welding may be a better solution if the weld is done correctly and pressure tested prior to installation to ensure there are no pin holes and so on. I would go with the welding solution only if I replaced all 8 fittings with thicker material, and used a welder who has done this many times.

I removed / JB welded / SS fastener.
Should be good to go.
One of these in the right diameter makes cleaning the old epoxy out much mo easy..

Welding add more complexity with little benefit.
Pinning without removing / cleaning / "re-epoxing" the fittings in place is false economy.
Pinning after removing / cleaning / "re-epoxing" the fittings in place is the shizzle!

welding requires the parts be removed the fittings removed cleaned and reinstalled then either mig or tig welded. then pressure tested to ensure no pinholes are present. pros to this is its a permanent fix. the fitting will never come out and once tested wont ever leak. the con is its costly . engine has to come pout parts removed new gaskets and reinstallation then motor back in. i used my oem fittings and a pro welder who did a a1 job in the end 2 minor pinholes under testing fixed them never had an issue. present motor has jbweld in 1 fitting and 8 pins. zero issues with this motor.
either way works well if thought out and handled properly.

I can't see how you could remove the fittings without pulling the whole cooling system apart. Heating the fittings will not be good for the other seals and you would not be able to pull the fittings out with damaging them.

thats why i only sealed the blown fitting. didnt want to risk that. so far no issues
