The DR17 is the next evolution in Edelbrock conventional style big-block Chevy cylinder heads geared for the sportsman racer. They are designed to deliver consistent and reliable performance through the whole race season. These cylinder heads are based off our popular Victor 24 Gen II Pro-Port Raw design, but features a revised valve angle and location for improved flow and performance. The casting is Hot Isostatic Pressing (HIP) processed for superior strength, durability and exceptional finish quality. Requires the use of shaft rocker system. Tall-deck applications will require the use of spacers.

    Features Include:
  • 0.400" raised intake port for precise alignment when using a tall-deck manifold on a standard-deck block
  • Valve angle has been rolled to an unprecedented 17 for improved combustion and efficiency over the current conventional cylinder heads on the market
  • Includes a revised water jacket for maximum effort port designs
  • Other changes include a taller valve cover rail
  • Pro-Port Raw version #615469 is available for custom porting applications
