I ordered the Dynomax headers from summit, only issue i have is my starter gets hot and will not start and i have to wait till it cools down. I hope when i wrap them it will solve the problem.

i have some hooker 27" long tubes and they fit fine. No heat wrap and the starter still works fine though it is close. Mine is a highboy though so a little different than a regular 4wd.
And they were only like $160.

The headers that are on my truck are Cyclone, but I don't think they are around anymore.

I just installed them on my 71 4x4 with a 390. I did have clearance issues with the motor mount braces that attach to the frame on both sides. I was installing a fresh motor but I will say they would not be simple bolt on installs!
Of note, when I fired it up for the first time all the paint on them vanished in a cloud of smoke. I think they came from the factory with a coating of Krylon

Not ALL of Hedman's headers have clearance issues nor does ALL of their coatings vanish in a cloud of smoke. You get what you pay for. The Elite series are fine for at least a 76 F250 4x4 and have had none of the issues you have described.

I made some really good looking mods to the braces, I will post photos if anyone is interested. The starter... What a headache. I had to lift the engine via the hoist, remove mount brace and install starter, get header in, lower engine and button it up. I hope that starter never fails because removal and replacement will be the same.
My guess on header clearance issues may be because the braces are different from year to year. Otherwise they fit perfectly.
And then I found the headers had about 1-2mm clearance between the braces.
