Read the shipping policyOur header flanges are 3/8" thick and all of our primary tubes are constructed with 16 gauge tubing with a 2-1/2" 3 bolt collector ring. Each design is available in a non-plated version, ready for your painting or custom coating. Our written guarantee states that if the headers do not fit your engine conversion exactly as you see fit, then simply return them for a full refund. You will only be responsible for the freight charges. We do not warranty the chrome plating on our exhaust systems, and the use of aftermarket header wrap products will void the header warranty. Thirty-four years of continual fine tuning and adjustments have made the Advance Adapters headers a choice for all engine conversion installations.
NOTE: These headers do not fit with Advance Adapters conversion bellhousings or factory GM bellhousings, and are not recommended for any manual transmission applications due to fitment issues and interference !!!!
