Pinning vs Welding and what else to do?
All pressure tested now for reassembly and hopefully back to the fun.
Find an FAA certified aviation welder in your area. These guys are excellent at welding all types of aluminum. Our local guy has welded probably 20+ sets of pipes over the last two years without any issues. Pretty much all track cars. He has cut a beer can in two on a band saw and welded it back together. He's goooood.

If I recall it was $1000 for our FAA guy to weld all 8 fittings after we delivered the manifolds to him. He removed the old fittings, cleaned everything, and welded the fittings in place.
Welding is nice if you have new or extremely clean parts. Saying this welds are subject to porosity and vibration cracks. Pinning will do the job just fine. I had the choice with the engine apart with clean new parts and choose to pin. What do I know about welding? I held ASME A,R,S and PP stamps and held the title of Quality Control Engineer. Either will do the job. It comes down to how you choose to spend your money.

I thought my guy gave me a deal and you just confirmed it. Delivered manifolds and he did everything else and they look great and pressure tested great as well - $120.00 - I would have paid 5x's that for this quality work. I guess some people are still very reasonable these days.

I have a Tip otherwise a clutch would make a lot of sense. Has anyone considered the method in this video. they knurl the ends of the tub and then JB weld. They said that they do like to introduce any additional holes.

contact engine builder supply and ask them. they can build the kit any way you want it. if your doing rods and head bolts now they have a complete rebuild kit with seals , rings, gaskets etc for about 1600$
I've already got all that going on... I'm referring to the kit of 8 bungs, etc to take care of my coolant line repairs. I did find a couple online shops selling a kit of machined bungs..... seems going rate is about $180 for the set.
Personally, I would weld them and not have to ever worry about it again. As long as you pressure test the welds, it's easy enough to re-weld a pin hole until it's gone and move on to the next piece. IMO, it's the proper way to do it and should last the life of the vehicle.
