High Performance Porting, Valve Guide Upgrades, Spring Upgrades, Valve Jobs & More For Subaru OHC, EJ20-25 DOHC Cylinder Heads

WHETHER YOU’RE RUNNING A ROAD RACE, DRAG RACE, OR STREET RACE HEADGAMES CAN PUT A RELIABLE HEAD AND CAM PACKAGE TOGETHER FOR YOU!

We port the combustion chamber to not only match the 2.5 but also reshape the chamber to rid it of any hot spots that can cause detonation.  Your tuner and your engine builder will thank you for it!

This means more boost, more timing, and ultimately more power from your swap!!

Our HeadGames Motorworks “Subi Packages” are built on experience and unmatched reliability.  Known as world renowned performers, making for the absolute perfect option when looking for a set of heads that will deliver for years.  Our HeadGames heads are known for their quick spooling capabilities with dyno graphs chock full of area under the curve.
