kauffman aluminum high port head

 

The KRE Aluminum High Port cylinder heads are the best choice for Pontiac race and / or MAX EFFORT street applications. The KRE High Ports have been on the market since April 2005 and they have proceeded to dominate the Pontiac race market! This head is NOT a modified KRE aluminum D port, this is a completely different head/casting!  The heads feature raised intake port openings and extended intake flanges for improved flow, while retaining the stock location, making them compatible with most standard high performance Pontiac manifolds and round port style headers. The CNCed fast burn heart shaped combustion chambers are VERY efficient as they incorporate some of the same improvements as the KRE Aluminum D Port heads.  Oil drain backs have been inproved as well to prevent excess oil from laying in the rocker area.  The heads will bolt to ALL traditional Pontiac blocks & aftermarket Pontaic blocks, and do not require special offset lifters or rocker shaft systems.

Other features / improvements include:

  • Exhaust port is standard Pontiac round port configuration
  • As cast with a 45cc chamber and delivered with a 56 cc, 64 cc, 74cc or 80 cc CNC chamber
  • Utilizes standard pushrod location for 3/8 pushrod – typically around 10.300 long
  • Rockershaft versions available upon request (shafted heads use a T&D 9028 shaft system .700 offset)
  • As cast heads flow around 330 cfm on the intake
  • 2.20 Intake valve and a 1.70 exhaust valve
  • Ferrea 6.200 Valve length
  • Valve angle is 14 degrees
  • Minimum bore size of 4.150
  • Stock port heads use a TIP-120230 intake gasket (specifically designed for the head)
  • TIP-120240 intake gasket is used for most standard pushrod location heads
  • Oil drain backs are positioned to allow for a more complete draining back of the valve cover area preventing oil from standing on the valve seals
  • Pushrod tubes are designed to accommodate 1.65 rockers without grinding on the heads
  • CNC ported versions of 365, 380, 400 and 430 cfm
