UPDATE #2: HEADERS FOR A 91 G-20 WITH A 305? - February 16th 2022 10:24 pm
Been looking around for headers for my 91 G-20 (305; automatic). Thought I found a set at Gibson but contacted them and they said they would not fit the van.....so I am asking if anyone knows of a set that will fit my van without "ANY" modifications of any sort.... bolt on clean nice & easy....would rather have a short or medium set.....feel that long headers might cause problems.
thanks
UPDATE (sorry…should of updated this sooner) Anyway headman had a set that fit perfectly (well for the most part…LOL)…had to have the right side of the rear trans support modified a bit….it was blocking the location where the exhaust pipe runs through. (also used a set of heat sleeves for the plug wires but so far so good)
UPDATE #2: Had to replace the regular O2 sensor with a heated one….engine would not idle correctly (seems to run OK other wise)….was not getting hot enough being further away from the engine.
thanks
