ALL PRO is Borowski Race Engines' vendor of choice for heads that can generate and contain lots of horsepower. Their heavy castings and high quality alloy clearly differentiate them from the competition.
We buy raw castings and first do 5-axis CNC porting. The next step is a CNC valve job on our Newen Contour. This machine is able to contour the bowl, cut the valve angle and un-shroud up to the deck with incredible precision.
These heads come fully assembled with Manley Severe Duty intake valves, Inconel exhaust valves, Manley springs, locks, retainers and locators.
Be sure to watch the chassis dyno video (courtesy of Vector Motorsports, Brighton MI) to the very end to catch the numbers being put out by these heads.
Also available with Xceldyne titanium valves
