fixing a bent header?

I used o2/acetaline

and it does get verrrrry hot

just b carefull with the pressure.

we tried propane and it just did not get hot enuf.

I have a Noleen header and my freind that this jig belongs to has the T-4 setup front to rear.

Yes I think that they are thicker by quite a bit.

Maybe just needs to be hotter with less air psi.

We used between 75psi and 80psi

Well that makes sense, thats what I was thinking was it wasnt hot enough! Since Acetiline is much more expensive we will be going to a welding shop with our jig tomorrow to get it straightened out. Thanks for your help!

Well my header turned out awesome...it is no longer a HUGE crease but now a little line. Another 10 more mins and I could have gotten it perfect, but I didnt want to use all of my friends oxyacetiline (even though it was a very large tank)! I used about 60-70 PSI of pressure in my header and it worked great, it took a total of 20 mins! Man that stuff burns hot, I was wearing welding gloves and it still was like an oven ,it also was in a hot barn (gotta love the TX weather right? LOL)

I think as long as you keep the bead of the flame (the neon blue tip) about 4 inches away from the header at all times and move it around alot...it will not blow a hole in your header! Well I appreciate all your tips and suggestions! Thanks,

i have a 98 400f with a fmf header and pipe. I had exhaust works fix my smashed header it took only a day and you can't even tell it was ever bent or smashed. The best part was there was no discoloration.

I highly suggest trying him.
