SCAT PATENTED 356-T7 SPLIT-PORT CYLINDER HEAD ASSEMBLIES

FEATURES INCLUDE:

  • 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 highlift ratios
  • Heads can be used with injectors or popular Weber & Dellorto Carburetors & Turbo Chargers (a must for Turbo Engines, no more torched heads)
  • Heads are available as basic kits or as complete custom assemblies, ported and polished
  • The universal casting made from aircraft-quality 356-T7 aluminum can be machined to each customers specifications for either the TYPE I or TYPE 4 engine.
  • 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 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
  • INTAKE AND EXHAUST VALVE SIZES RANGE FROM 32.0mm to 50.0mm
