Our 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 either a polished stainless steel or a non-plated version, ready for your painting or custom coating. NOTE: Our headers are not designed to fit Chevy small blocks with angle plug heads. 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. SMALL BLOCK CHEVY HEADERS: The Chevy headers we offer come complete with header flange gaskets, header bolts, and collector rings for the exhaust shop.
