Speedway Motors 9300102H Details

Rodders and racers are known for wedging big engines into small spaces, so these big-block Chevy shorty headers are designed for applications where space is limited. They offer great flow in a compact package and will fit where many other headers won’t. These block hugger headers make difficult installations easy. These shorty headers are ceramic coated headers.

  • Fits round-port cylinder heads
  • Compact design fits a wide variety of applications
  • Made from 16-gauge tubing
  • Includes reducers, gaskets, and bolts
  • 1-3/4” primary tube diameter
  • 2-1/2” collector diameter

  • Will not fit 55-57 Chevy cars, Camaros, or other modern vehicles which have a crossmember below the engines center two exhaust ports
  • Fits standard deck big blocks only



Warning: AHC coatings will burn and be damaged at exhaust temperatures above 1300 degrees. A lean fuel mixture can generate exhaust temperatures exceeding 1700-1900 degrees. If the coating is damaged due to a lean condition, the coating will not be warranted, but can be recoated for a fee.
