• Used with SCAT KILLER CASE or ALL VW TYPE 1-4 ENGINE CASES
• Designed for use with either needle bearing style rockers (.687 shaft) or standard size (.707 shaft ) rocker arms with stock or hi-lift ratios
• Heads can be used with injectors or popular Weber & Dellorto Carburetors & Turbo Chargers (a must for Turbo Engines, no more torched heads)

• BORE SIZES RANGE FROM 90.5mm to 105mm Type IV
• 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 OEM style performance heads. Basically, with the reduced valve angle, OEM 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 OEM stud thru clamping block design
