    Do they fit right on a K5? My manifolds look to be VERY restricting, so I thought maybe I could get these to help it out a little bit.

    If you had them on an '89 then does that mean that those cheap headers have the plugs for the TBI system? If so did they work good?

    Personally I wouldn't put on a "cheap" part. "Cheap" headers will succeed in is pissing you off. As soon as I can afford it I will swap out the "cheap" afterburner headers that were on my k5 when I bought it for some Thorley's.

    I've got the 150 dollar headmanns on my 85 3/4 4x4 chevy. The passenger side header fits great. The one on the driverside hits the rear spring shackle. It actually rubbed a hole in the header and melted my polyurethane bushing. I had to weld a 1/2" steel plate to the header to keep it from putting another hole in it. I've replaced the bushing twice now and it continues to melt it. Every set of headmanns i've seen hits the shackle. I would think that if they ever put them on a truck they would see right away that they hit and maybe angle them differently. They did add more power in the mid to upper rpm range and sound awesome. You might consider going with shorty headers instead of the long tube ones. You won't have to worry about them hitting at all.

    I really think you'd be better off getting GOOD headers like Doug Thorley TRI-Y headers.. [​IMG]

    what's wrong with some Hooker Headers? I am curently running the Summit brand header and it fits well in a '77. If you have a '89 you should go with the JBA shorty headers.

    So what would fit right on an '85? I don't want to melt any bushings...and I want the cheapest i can get...shorty or long tube doesn't matter to me.

    Do the JBA shorty headers come equipped with the holes for the o2 sensor for the TBI engines? if so how much do the run for a set?

    If you got a set of headers that did not have the o2 on the header, You could get a set of Collectors with that fitting.

    I bought a set of Dynomax from jeggs, under $100, they fit just fine. I've had them about 6 mos. now and have had no problems.

    Tell them you want the Hedman headers for a 4X4. I think they run about $25 more. These will tuck up a little higher and you will not have problems with the spring hanger. I have had these for 3 years without problems.

    i just put the dynomax ones on this weekend, install was a breeze, only thing i had to do was trim a touch off the rear shackle bolts to give me plenty of clearance, i could have just swapped the bolt through the opposite way but that woulda been too much work /forums/images/graemlins/rotfl.gif /forums/images/graemlins/k5.gif
