Thread: LT Headers

  1. #1

    Default LT Headers

    Looking to install LT headers on my 86'. Anyone have any real world advice about the JEGS brand

    says in the description these are 16g which would be a plus. I wonder who boxes/brands these for JEGS?

    I've used these. They fit well.

    Can get the ceramic coated version for $333.

    I had a set on some P heads. If I can remember correctly the only issue was number 4 cylinder. I cut a chunk off of a stock 5.0 header and used it to space out that tube. Gasket, header flange chunk, gasket, then Flowtech header. It worked without leaking. Passenger side header has individual tubes to get the header in around the starter without having to jack up the motor. Driver side had one removable tube that snaked around the steering shaft.
