These compact, tight-fit headers are designed for Small Block Chevy (S/B Chevy) engines with round port heads, making them ideal for applications where space is limited. Featuring 1-1/2" primaries and a 2-1/2" collector, these block hugger headers simplify even the most challenging installations.

Armor Hot Coating (AHC) is a heat-resistant ceramic coating applied to the exterior of the header. It reflects heat back into the header tubes, helping to retain exhaust heat and improve exhaust flow. This can lead to increased horsepower, while also keeping the headers rust-free, cleaner-looking, and more durable with proper care.

This coating can withstand exhaust temperatures of up to 1300°F.

  • Designed for round port S/B Chevy cylinder heads
  • Driver side collector is approximately 2" from the pan rail
  • Passenger side collector is approximately 1/2" from the pan rail
  • Flange thickness: approximately 0.212"
  • Includes reducers, gaskets, and bolts
  • Will NOT fit angle plug heads
  • Will NOT clear 'clam shell' style motor mounts (common on 1973-up Chevy applications)

NOTE: Most tight-fit applications require shorty spark plugs for proper clearance like those offered by Accel.
