Enginetech cylinder heads are available as new castings and as remanufactured bare heads, giving engine builders the choice that fits their application. Bare heads include new valve seats and guides installed, making them ideal for situations where the original head has cracked or failed but the valves, springs, keepers, and retainers are still serviceable - simply transfer the existing hardware onto the new or remanufactured casting. Each Enginetech cylinder head is engineered to meet or exceed original equipment specifications for chamber volume, port dimensions, guide diameter, and valve seat geometry. Always verify the part number against your engine's casting number, production date, VIN code, and any application-specific qualifiers before installation - multiple head configurations often exist for the same engine family.
