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.

We have even flow tested what to blend and what not to blend. Because a valve job isn’t just a valve job. It’s the most important job in the cylinder head that your machinist can perform. Don’t leave it to just anyone...

Instagram post 2098813703613058350_548945097 Machining these Subaru heads to fit some big ass cams! When you run many of the larger aftermarket cams in a subaru the head needs to be clearanced for the lobe to turn 360. If not, it becomes a failure! Sometimes the lobes actually don't hit, but are so close to the bucket hole on the sides that the clearance will not let oil run across the bucket and you get a bucket failure!
