• THE PATENTED "SWIRL & ROLL OVER" DESIGN
• Breakthrough in VW Head Technology

1. The valves of the Split-Port head open more towards the center of the cylinder "ROLL OVER" which increases intake and exhaust mixture flow by more than 20% over the best O.E.M. style performance heads. Basically, with the reduced valve angle, O.E.M. head at 9 degrees compared to the SPLIT-PORT HEAD at 6 degrees, the valves becomes unshrouded.
2. The "SWIRL" combustion chamber fills and scavenges the cylinder greater while speeding up the flame travel and reducing

• Improving cooling, fins all the way around the head (360° COOLING)
• Even torque and better sealing between cylinder liner and head because EQUAL LENGTH CYLINDER STUDS are used and each head is independent
• Cylinder head TEMPERATURE is not effected since each head is INDEPENDENT
• Stronger rocker arm shafts. Each independent shaft is supported by 3 bosses compared to the less durable O.E.M. stud thru clamping block design
