Unhappy 250 w/stovebolt cast headers, help-who has one?

I'm looking for someone who has a 250 in an AD with Tom's Stoveboltengines.com cast ceramic headers installed. Mine hits thhe steer boxno matter what I do. I have pulled all the head studs etc and still no room to squeaze it. Let me know if you have a better idea than the torch and building different motor mounts...GRRRRR!

Spoke to Tom @ Langdon's ( supplier of the headers) He said when they know that they are being installed in a A.D. truck, they shorten the forward header 3 inches for the customer. Took the truck and headers to the exhaust shop, they will cut it and fit the collector , then I will take the 2 pieces to the machine shop and they will heat them in an oven, weld them with nickle/Copper rod and cool them down in the oven. Small speed bump, but I get to keep the headers!

Hey Jon, I'm confused (as Usual), these headers you have from Tom ,are they not cast material? How do they shorten them? Do they have 2 different castings or do they just wack off 3" and and re- weld the collector back on? Seems kind of odd to me. Wouldn't a set of Clifford shorty headers work in your situation? Like these

Yes, "new" castings can be welded successfully says Tom and our local machine shop. Used ones, not so much. Carefull heating and pre-cooling, using Nickle -Copper rod are the trick. As I type this they are warming up in the oven.

Thanks for the side shot on the Clifford shorties, they would have worked perfectly!

Chopped the header and got it turned to fit. Took both pieces to the machine shop and they pre. Heatedto 700 degreesand welded them up. Put them back in the oven and let them cool down slowly. For over an hour. Bolted it up and towed the Burb to the exhaust shop. They called at 4..all done. Picked it up and worked a couple hours fumbling a coolant leak, ran a choke wire, finished the Lokar pedal swap and hit the key....set the timing and runs like a scalded dog!
