full length headers on 302

Is anyone outthere able to tell me why companies keep telling me that full length headers won't work on a '94 f-150 with 5 speed man? i'm replacing my I6 with a 302 and would like to put a set of headers on it. partly for power, and partly because both manifolds i got with the engine are cracked. any reasons why they wouldn't work would be more than i have right now! tahnks in advance.

I think it has a lot to do with not modifying the factory exhaust because it has emissions junk like O2 sensor & cats. I think you can get full length headers for 80-86 trucks, these should be able to clear the body & frame ok, only thing to check clearance is the hydraulic line to the clutch, and by the fuel filter/pump on the driver side of the frame.

loudfords,

i plan on running a full aftermarket exhaust, (no cats, sshhh), and it will all be custom bent. will the everything still run smooth if i remove the o2? i know that you can buy collectors with o2 fittings, so would these be a good idea? sort of nieve to emmision junk. any words of wisdom would be greatly appreciated. sounds good so far though...

You will want the oxygen sensor. Without it, the computer doesn't know what to do with the fuel mixture.
