1948 ford f-6 226 flathead cracked Exhaust Manifold
I have a cracked Exhaust Manifold, near the base where it attaches to the exhaust pipe.
I had tightened it too tight and it was corroded.
Where can an exhaust and intake manifold be found. I can't find them. The older posts links are no longer valid.
I thought I might replace both. But desperately need an exhaust manifold.
It's a 226 flat 6, one side manifold.
Thank you

I don't understand why though. Almost everything is re-mfg now, either here or over in China. Almost everything is available, but of course these.
I can try to have it fixed?

About 25 years ago, one of the Packard clubs had 1932/39 V12 iron heads reproduced, are still trying to recoup the cost.
Many of these cars came with aluminum heads, attempting to remove them is a PITA, some people use an ax!
So replacement iron heads have been hard to find for decades, but there just hasn't been enough demand.
And btw: The 215/223 OHV I-6 exhaust manifold is very prone to cracking, the same manifold is used on 1952/64 cars and trucks.
There are far more vehicles existing with these engines than there are with 226/254 L-heads. No one reproduces it, none are available NOS, finding a user that isn't cracked is almost impossible.

It costs 10's of 1000's of dollars to reproduce a single part, but if there's next to no demand, no one is going to bother.

I don't care what ford did, A 215 manifold will not allow you to connect to a 223 head pipe and a 223 manifold will not allow you to connect to a 215 head pipe. Just the facts, you might want to put a little note in the 1963 parts book

Chrislynn5, I bought two donor 226 engines trying to find a good exhaust manifold. (my original on the '49 was snapped completely off at the flange)
The first donor engine looked great - FROM THE FRONT - but when I removed the manifold pair, it had a huge crack in the back. It would have been impossible to see because of the way those things are mounted with the valve plates obscuring the view, and the dark crusty color of the steel. So basically I paid $800 for a decent oil pan, flywheel, water pump and some other trinkets. The rest of the engine was used-up. I thought I could get a lot of parts from it but it didn't pan out. The next donor engine cost me $300 but it had a fair condition manifold, a nice carb and more trinkets I could use some day. I'm sure the manifold is weak since it is pretty badly pitted but it has no obvious cracks.
I'm sharing this to anyone who is looking for a manifold. If it's still on the engine....try to remove it first so you can see the back side. I heard that welding cracks as a permanent fix on these is nearly impossible.
Good luck, hopefully a member here who has a good extra one will contact you.
And as long as we are talking 226 hard-to-find parts I have an extra water pump in good shape if anyone needs one. And no, I won't charge $800 for it. I've accepted my losses on that deal.

Look around, you will find one. Part of the challenge / fun with a 226 is finding parts. Be careful when torquing any engine stuff or really anything 65 years old and follow the torque guidelines in the manual. It's easy to get carried away and snap something off or crack something. My dad does it all the fime LOL....

The fun would be driving it. Winter is upon us, maybe, it's 86 tomorrow here in Atlanta.
