These heads feature a symmetrical port design for the Sportsman racer. They are similar to the Pro Stock DCE3 Cylinder Heads and are CNC port matched to popular Edelbrock, Brodix, CFE, Dart and Sonny Racing Engines blocks. They have more oil drain backs than traditional spread-port heads for improved oil flow and distribution. These cylinder heads include a new water passage design for more efficient cooling when matched with an Edelbrock BV3 valley plate and also retain the traditional water passage for a variety of applications. These cylinder heads have a redesigned valve train geometry for improved stability, delivering consistency and reliability. The casting is Hot Isostatic Pressing (HIP) processed for superior strength, durability and exceptional finish quality..
