Headers

[Rome03]

Been digging through a bunch of old threads in reference to headers. Seems like the Hedman headers are pretty well liked, but require messing with shifter linkage on auto trans?

I’ve got an 81 K10 with a 350. I’m about to start tackling the exhaust. I’m looking for input for some long tubes that fit well without needing a ton (or any, ideally) of modification to get it to fit.

Thoughts?

I have the Summit brand ones on my 85-K-10. The ceramic coating hasn't held up very well. I don't have the support rods that run from the motor mounts to the trans bell housing.

There's two main styles of Hedmans for our trucks. One style hangs low and is super easy to install, but they tend to rub on the spring shackles. The other style tucks very well but is harder to install since starter removal is required. These are the ones that tend to interfere with auto shifter linkage. But the linkage can be retained with some creative tweaking and or a well-placed "s" in the exhaust.

Iirc, it's mostly an issue with the 700r4, but that makes no sense to me because I "thought" the linkage was in the same basic location.

Many many moons ago, I had Hedman’s on an ‘80 K10 with a 350 / 4spd, they required zero mods and had no interference with the clutch linkage.

Edit: my headers were a per the application set, I’ve been told 1st gen Camaro headers fit without hanging as long but I’ve never done it.
