High Performance Porting, Valve Guide Upgrades, Spring Upgrades, Valve Jobs & More For Mitsubishi 1st, 2nd, Evo 8-9 4G63, 4B11T, 6G72, 420A Cylinder Heads
Our HeadGames Motorworks 4G Packages are built on experience and unmatched reliability. They are known for being world renowned performers, making for the absolute perfect option when looking for a budget minded head package that will deliver for years.
Our full port is known for its quick spooling capabilities with dyno graphs chock full of area under the curve. We do this by going against the grain. This head is rationally ported, with air speed in mind, and we utilize the factory size valves up to 1000whp! We came to this conclusion not by mere thought, but by careful action. And testing! Don’t be fooled by the oversized valve myth.
We also offer 2 pocket port packages. The Pocket Port and the Pocket Port ‘R” which is coupled with combustion chamber reshaping to aid in getting rid of any ugly detonation. The HeadGames Pocket Port ‘R’ Package is a proven 8 second, 1000whp performer!
