Dimples, dings, and dents in Header tubes. Any good tricks

A BIG PAIR OF CHANNEL LOCKS WORK GREAT W/O HAMMERING IF UCAN GET THEM ON THE TUBES IN THE RIGHT POSITION, after heating . NEED TO USE SOME SORT OF SHIM TO GARD THE TEETH THO---
dam caps button just jumps out there much like a telephone pole when I was polluted once !

I researching how close my headers will fit with the Borgensen box. If what I am told is correct it will be a minimal amount of manipulating the headers to make it work..... Why TTI didn't accommodate the 1 3/4" for PS with a BB conversion is beyond me. The 2" is a whole different animal but whatever. It's hotrodding 101. I do like the pliers idea though.....

Thanks,
JW
