While re-installing my header on a 1973 Spider it cracked! It was difficult to a line to the studs on the head. This obviously caused header to not be horizontal to head. On #4 exhaust the “ear” caught threads of stud & cracked during tightening the nut. I should have noticed🤷🏼‍♂️
Is this repairable (weld) or replaceable? Do I need to call APE or any part available out there for sale?

I've got a pair i don't need to sell but if you get stuck let me know. APE would be a good trial. These are getting broken on a regular basis because the new pipes need tweaking to mount.

Thank you & I will let you know if binding. I've got a couple of Alfisti looking for me as well. I do appreciate your reply! And yes, they do need a tweak or two. It was my mistake in hurrying..

It can be brazed or brass welded, but to be honest there must be plenty of Junior exhaust manifolds about, I have a spare and a set of Euro Alfetta headers as well

APE is a good place to start

it "can" be repaired the question becomes is it worth repairing.....

a GOOD machine shop should even be able to weld it up, and youll need to have it decked once repaired anyway

Dad brazed the self same ear on my very first Alfa manifold more than 30 years ago now, when I sold it 15 years later it was still running fine, but yes it's not always the perfect solution & welding cast iron isn't for everyone.

100% right, the Alfetta ones are totally different, not compatible.... I shoulda been more specific Uncle --> I have a spare of each & a spare 750 4-into-1 as well

I do appreciate all the comments, opinions & ideas. Trying the best to cover the bases & weigh the options. I don't want to make a "dumb" mistake again so I'll put my attention where it does best.
I do have a good friend & an excellent welder here in Vegas but he on leave until work picks up. He is their specialist when it comes to stainless and can easily handle the cast iron exhaust. But with his equipment at the shop,, well he's gotta be in the shop.
So I'll wait or buy used. It's not life or death. :coffee:I think I'll have a cup

Just don't make the same mistake twice. I had my front section installed by a shop and warned them it might take some tweaking .. they were aware of stresses of ill-fitting pipes putting stresses on cast iron headers.. Sure enough they needed to tweaked it without heat and said they thought shipping might have put it askew..I personally think they are all like that. They should fit with NO grunting whatsoever and if they don't, correct it. Just a friendly heads up.

That I concur, quit “doing the same thing over & over”, 😩
Yeah I’ll be much more careful!
Thanks to all that posted! My bud in San Diego has ample supply & I owe him a delivery as well, so, soon to be solved.
A thank you goes out to goats!
