Crawford Street Spec Cylinder Heads – Subaru Cylinder Head Upgrade

The Crawford Street Spec Cylinder Head Service is the ideal choice for Subaru owners who need more than just a stock replacement. Designed for street and light track builds up to 450–500 whp, these heads deliver reliability, efficiency, and improved airflow — making them the perfect OEM+ upgrade.

If your factory heads are damaged, worn, or simply not up to the demands of modern tuning, the Street Spec service provides freshly prepped heads with proven durability. Built with the same race-tested methods trusted in Subaru of America motorsports programs, these heads form a rock-solid foundation for moderate turbo upgrades and spirited driving.
