P2P Racing Stage 4 EJ Cylinder Heads - Dual AVCS
P2P Racing's Stage 4 head package matches GSC dual springs, largest lift/duration S3 cams, +1mm Intake and Exhaust valves and a full port to maximize airflow in the higher rpm range. P2P Racing replaces the stock seats with a proprietary seat that is larger in diameter and deeper in the head to remove the risk of cracking seats with +1mm valves. These heads are far superior to stock heads and are made to last. The New OE castings are taken to our in-house machining center and the valve seats are cut with radiused multi-angle seat cuts that allow for maximum airflow, while retaining seat longevity. The porting is hand ported as this allows for the most precise flow matching capability. All castings shift slightly, and if a head is not ported by hand and tested, the results in each runner may vary if, for example, a CNC port without hand porting is done. The spring and cam combination is perfect for our stage 4 or stage 5 short blocks and their ratings.
P2P Racing's engine program has been proven time and time again on and off the track. P2P Racing has had countless race hours on these engines as well as millions of street miles that prove you can have the best of both worlds. P2P Racing balances and blueprints everything in these engines. P2P Racing's goal is to provide the customer, you, with entry to a level of engine building normally found in super cars and race teams. P2P Racing's goal is your success, P2P Racing is not afraid of any problem, and will assist you with any questions.
Why Choose our Stage 4 Head Package Over the Competition?
All machining, cleaning, and assembling are done by a degreed engineer. P2P Racing provides a level of artisan craft in our engines only found in race teams and super cars. The experience we bring to P2P Racing's engine program is unparalleled in the industry. P2P Racing blueprints the entire assembly of the motor to within .0002 of P2P Racing's specs. It is incredibly important to balance your motor to increase the life of your bearings. It is highly recommended to run a Fluidampr/ATI crank pulley or OEM. Do not run an aftermarket solid crank pulley. All of our inspection equipment is high quality, either from Starrett or Mitutoyo, and is sent off yearly for calibration to a qualified cal-lab.
