Model Difference Confusion for Header Application

1985 F150 XLT Lariat 2WD, 302 4V carbureted engine

I am looking for a good set of headers, and I have decided on the Tri-Y long tube header design. Summit has a set made by Doug's that I really want, but their "application notes" is confusing to me. The description reads:

Item # DOU-D6648Y
Headers, Tri-Y, Steel, Ceramic Coated, Ford, F-250/F-350 Pickup 1980-87, 5.0/5.8L, 2WD, Pair

Notice that the F150 model is NOT listed. Does anyone have any idea why? My truck does have the 5.0, and it is a 2WD, so what is the difference between having a 5.0 in an F150 vs. having a 5.0 in an F250 or F350? Could this be a misprint? Did the F250 and F350 even come with a 5.0?

Jeg's carries the same set of headers, but their description is just as confusing:

D6648Y (same as above)

Fits:
  • 1980-87 F-150 4WD
  • 1980-87 F-250, F-350 2/4WD
Notes:
  • Will not fit F-150 2 wheel drive.
So now we find out that Jeg's claims that these headers WILL fit the F150 4WD model but NOT the 2WD model, whereas Summit doesn't list the F150 at all. Does anyone know why? I mean, why would a company make long-tube headers for a 4WD model truck and NOT a 2WD? Seems kinda backwards to me.

I want a set of long-tube TRI-Y headers for my 1985 F150 2WD!

My best guess would be front end changes / Differences in axles,

As an f-150, you have coil springs and radius arms correct ?
F-250's are leaf sprung thus allowing more room to install headers

In the same factor, F-150 2WD is the same as a 4WD, i think it just has a differnt cross member for the TTB junk in the front end. I belive the radius arms and such are all in the same location.


LandLproducts.com quote

"302/351W Chassis Exit 2WD/4WD
1980-96 Bronco 1980-95 F150/F250/F350 Complete With Hi Performance Header Gaskets, Collector Reducers and Installation Hardware. 1/2" Thick Flange 1 1/2" Primary Tubes 4 into 1 Header " $549.80

Or save 100$ and get black painted set.

I would assume they just didn't bother typing up

You could allways call LandL and ask them
