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.

Special Notes:

  • Inside the frame rail header
  • These headers are not legal for use on pollution-controlled vehicles
  • Note: Our exhaust headers are designs for use with Advance Adapters branded engine mounts. If you are using another company's engine mount kit or if you have fabricated your own, Advance Adapters cannot guarantee the compatibility or fitment of our headers with said mounts.

Did Not Fit.

These did not fit my application. The right side did but not the left. Both headers were the same shape which doesn't work. The left side was hitting the engine mount. The company was very responsive and gave me an RGA # to return them.
