I was very impressed with the flange thickness and overall thickness of the headers . Took a bit of force to dimple the one tube even heated . Now I need to get some pipes for the exhaust

I've run headers on vehicles in the past, and leaks were always an issue. I've stayed away from them for decades because of that. I'd be interested to know if those stainless headers ring less than the regular steel type. I'd like to get the engine in my truck rebuilt sometime in the future, and wouldn't mind seeing the cast iron manifolds gone, but that ringing is unacceptable to me.

That hasn't been my experience.
Tri Y on a 454 haven't touched them since 2017 when I bought the truck.

And 4 -1 on a sbc been together since 2016 zero maintenance
nor leaks.

Dougs tags on both sets.

I've been very impressed with these crusty old headers, I used copper gaskets on the heads and collectors and added Permetex copper colored gasket sealant to them.
I also cut the metal bars between the ports because I read that would help to prevent any metal warpage from unsealing the ports.
Must have done something right because I installed the headers around 1999 and they've sealed perfectly ever since.

Oh yea, it has kind of warmed up around here today so I waxed the truck.
Stuff still hasn't dried as of this writing.
Thought I'd give the ladder a try to wax the roof and clean the windshield for some reason.
That worked out OK.

Maybe it's internet headers that leak.
I don't know..

Removed the old exhaust setting it aside for the 68 that I’m putting the old motor in

God I hope not, now that I've posted they'll probably start leaking.
...I got some spares standing by.

Drove my '69 Nova from Mississippi to Washington one time and the engine started knocking!
Every steep hill I climbed the knock got louder and I just knew a rod was coming out the side of the block at any moment!
Made it home and discovered that some stupid header bolts had come loose.

ETA: As a side note I've never had to re-tighten these header bolts, as a matter of fact, I never even checked them so the bolts are probably rusted in the heads by now...great.
Heck I always thought they needed to be tightened again from time to time.
