8.1l Headers

[Gilderbeast]

What longtube headers fit for the 8.1l/4l85E/NP241 swap in our trucks? I have a 80 K30 with 4" lift.

It's my understanding that standard big block headers fit.

Doug's makes a set of long tubes for the Chevy Workhorse RV chassis. Have no clue it they would work or could be modified to fit.

I have standard big block headers from a 454 on my 8.1 swap, required a small amount of heating/bending to clear frame rails
