KRE Billet heads are designed on a state of the art cad cam program and machined in house on a 5 axis cnc machine. At this time they have 4 different Billet programs.
1. The original KRE billet head that Jeff is running on his digger. This was the predecessor of the KRE high port casting
2. The KRE Warp 6 canted valve head That Mark and Bill Mellott are campaigning at this time. Plans are for a casting sometime in 2009
3. The WARCHIEF HEMI The ultimate head for blown applications Bill will run these on his Pro Mod when done. Quite a bit of interest at this time will have to see if it is financially feasible to make a casting in the future.
4. The Warchief 5 A RAM 5 style billet head that was just finished. Will have to see how the racing public takes to this new design
This is Kauffman Racing Equipment line of Solid billet aluminum heads. The following are aluminum cylinder heads that we make and offer to you for ultimate Horsepower gains. These cylinder heads are designed mostly for alcohol fuel racing with a blower and turbo charged engines. Our own testing lets us know if these heads are a good choice for up and coming water jacketed castings that we can offer at a lower cost for street to strip engines. All heads are machined in house on their own CNC Machines.

Pontiac Billet Hemi head
Pontiac Hemi - This head was designed for a MR-1 block with a 4.300 or larger bore. Port sizes are designed for 450-560 cid engine blown on alcohol making in the 2400-3000 horsepower range.
Pontiac Hemi - Setup with a 2.500 intake valve and a 1.950 exhaust valve. Flow figures in the 550 cfm range in the intake and 400 on the exhaust bring this head to the very for front of Pontiac horsepower potential.
Pontiac Hemi CAD
Pontiac Hemi CAD - Drawn from Master Cam software, the Hemi design is tested for valve, pushrod, rocker, springs and spark plug clearances. This insures us 100% use once machined in our 5 axis CNC machine.
Pontiac Hemi Rocker CAD
Pontiac Hemi CAD - Careful attention was made to the rockershaft design to accommodate the Pontiac block design. No modification is needed to the block like you would with a regular type hemi head. Proper rocker arm geometry is designed for lifts from .700 - 1.100.
Pontiac Warp 6 Canted Valve
Warp 6 - Here is the valve cover area and the exh. port locations. You can see a standard Pontiac valve cover isn't going to work with a canted valve designed head
Pontiac Warp 6 Canted Valve
Warp 6 - Here is the ultimate cylinder head for naturally aspirated engines. You can see the unrestricted intake runners and splayed valve design. Taller intake runners for better flow and fuel distribution. Valve arrangement for better flow, tighter heart shaped chamber design and spark plug locations for fast chamber burn
Pontiac Ram 5
Ram 5 - Newly designed raised exhaust ports for better flow and blow down. Designed for a T&D rocker assembly under a stock valve cover rails.
Pontiac Ram 5
Ram 5 - KRE made this updated design of the Ram Air 5 head in a billet version. Taller intake runners for better flow and fuel distribution.
