Looking to see if anyone knows of somebody who has a jig that knows how to straighten some manifolds. I have several Ford script ones that could use some minor attention Thanks
There are many threads about this. My favorite method involves a not useable block,some steel plugs in the ports that extend into the manifold. Clamp down tight. Put in good size brushpile. Set afire. Let cool down slow. You'll have to finagle a little with the 'locator'plugs to get them in a humpback manifold. Worked for me. No new manifolds were available then.
I think that is the way my cousin describe straightening my Kingston manifold.
Look on the Tulsa Model T club website, I believe they have a tutorial on the subject.
Best way I found is make four
discs that fit a junk block nicely in the exhaust ports tack weld a one half inch pipe across the discs end to end in the block with about a foot hanging over each end for a handle that does not heat up to much. Turn it over to check a manifold for an exact fit without a tape or a straight edge
using a set up like Tulsa T does and a rose bud heating one area at a time with some thought before heating because some ports are spread and some not the discs tell you exactly where to heat using the pipe jig several times lifting off and on without burning your fingers. They have memory so let it cool and check again a small correction might be needed
ill I think I saw something from Stever Jelf in Ks. He is a member of MTFCA, and with out his permission I cant give you his PHONE #.
You posted the same question in 2015 and got plenty of good answers back then. See here:
I have an exhaust manifold straightening jig that my dad made. It works great, but you can do a fine job using a Model T block as Dad demonstrates here:
I straightened mine using the method on the Tulsa website. I made a jig similar to what they used and it worked OK.
The downside is the cost involved using Oxy-Acetelyne. By the time you use up the gas and time spent making a jig you can just about buy a new one. They are a pretty good reproduction part.
The next time I need one I'll buy one.
I am interested in finding Model T or Model A people in the Rio Grande Valley of Texas as I spend the winter there and would enjoy visiting with them. Thank you.

Bill, take a run over here to Orange County and Long Beach and you can find plenty of T guys to talk to.
Better yet, Come over to see the Holiday Motor Excursion this year right after Christmas on Saturday 12/31 and will be gathering at the Santa Anita racetrack. you won't be disappointed if you like old cars and bikes.
Thanks Gene! I am certain I would have a good time in that part of the world. I have been to CA a number of times and I was stationed at Port Hueneme when I was in the service.
