Been looking around for some bigger headers and as most know there are not any manufactures making bigger primary headers for our trucks,Have contacted many companies,and all but one said nope....
Spoke to one of the guy's over @ Kooks and he suggested F-body headers.
He advised to do a search on the forum's, That some have done this.
Well??? know of anyone? seen some?
would be nice to add some 1 7/8 step 2" if even possible.

Any help would be great.

Quik had em. I thought he said they fit fine. I think beastmode or someone had some f body headers but not kooks and they had to do quite a bit of work to fit em.

damn those look almost similar to the pacesetter truck headers besides the #1 cyl tube goes across the others and might hit the steering shaft bolt.
