318/360 Magnum 1-Piece Port Plates

Required equipment for Spintech headers on 318/360 Magnum engines. The port plates account for the large primary design of the Spintech header to be used on the small-port Magnum head. The 3-piece Spintech plates warp and leak over time. This 1-piece design is much more sturdy and less prone to leaking. 

Available in standard or Edelbrock aluminum head pattern, hardware included.
