These long tube headers work with both automatic or manual transmissions in 1964-1989 Chevrolet chassis. Features 1-5/8" primary tubes, 3" collectors, and fits angled or straight plug S/B Chevy oval exhaust port heads. Built with surface machined thick steel flanges for a great seal and mandrel bent mild steel tubing. These headers are a chassis header and are meant to go inside of the frame rails on the 1965-1989 Chevrolet chassis.
Available with metallic ceramic coating. Unlike paint or chrome, metallic ceramic coating is easy to keep clean, resists rust and corrosion and will not discolor. Metallic ceramic coating also reduces underhood temperatures.
Headers come with installation hardware, collector reducers, gaskets and instructions.

Nice looking set
I contacted the service dept. with a question on these headers and it was suggested that I use these for added ground clearance.I needed them for a truck and these were for a car. It also said some modifications may be needed. They were right as nothing fit in the compartment of my truck. Well I made the changes needed and YES they give excellent ground clearance after redesigning the motor mounts and some welding. Not a good idea if you don't have the expertise, knowledge and equipment to make the needed modifications. Yes I am impressed with the fit and especially the added ground clearance as my truck is slammed to the ground. Thanks for the great advise and warning SOME MODIFICATION WILL BE NEEDED.

Did not fit my car
It may fit some cars but not my 66 Chevelle. I would have had to beat the tubes in to fit. May have to use two shorty plugs.

It would be a better fit if the collectors were welded on with the 2 bolt connection up and parallel to the floor pan.
