HeadGames Motorworks

We don’t just build cylinder heads—we build legends.
At HeadGames Motorworks, everything we do is backed by over two decades of blood, grit, and world records. From hand-porting in the early days to leading-edge CNC development today, we’ve stayed obsessed with one thing: turning airflow into horsepower. Our cylinder heads power some of the fastest imports and domestics on the planet—from 4G63s to Coyotes, Supras to Skidoos—and our name is stamped into builds that dominate drag strips, half-mile events, and standing mile records alike.
Whether you're chasing 500hp or 2,000+, we don’t sell you parts and wish you luck. We engineer the entire flow path—valves, guides, springs, seats, lash, all of it—with the same precision we use in our own record-setting cylinder heads. When we recommend a setup, it’s because we’ve lived it, tested it, broken it, and made it better.
We’re not a shop. We’re the Machine Room.
Where heads go in, and monsters come out.
