GTV-2 Cylinder Head - 94mm - Dual Spring (40mm Inlet Valves, 35.5mm Exhaust Valves)

These EMPI GTV-2 racing dual port cylinder heads are engineered for high-performance air-cooled VW engines built to 1914cc with a 94mm bore. Designed as a direct upgrade for twin-port engines, these heads offer a significant increase in airflow thanks to intake and exhaust ports that are 20% larger than stock, allowing your engine to breathe more efficiently and deliver noticeably improved power and throttle response.

Each head is fitted with dual valve springs to handle high-RPM use and aggressive cam profiles, making them ideal for performance street engines, off-road builds, or track-focused setups. The heads feature 40mm stainless steel intake valves and 35.5mm stainless steel exhaust valves, providing excellent flow characteristics and superior durability under extreme heat and load. The stainless valves resist corrosion and reduce wear, extending the service life of your valvetrain—especially important on engines running high temperatures or extended periods of full throttle.

Manufactured specifically for engines using a 94mm bore, these GTV-2 heads are designed for easy fitment onto most performance-built 1914cc engines. As with all aftermarket performance heads, proper jetting, upgraded exhaust, and a matched camshaft are recommended to take full advantage of the increased port size and airflow potential. For best results, always install with high-quality head studs, new gaskets, and check valve geometry during assembly.
