Type 4 Cylinder Head - 1700cc

This complete Type 4 cylinder head is designed specifically for 1700cc engines fitted to VW T2 Baywindow models from 1972 to 1973. Manufactured with stepped / oval exhaust ports and EGR holes, this head is ideal for restorations or rebuilds where the original Exhaust Gas Recirculation system is retained.

Featuring 39.3mm inlet valves and 33mm exhaust valves, this cylinder head delivers efficient airflow and balanced combustion, perfectly suited to standard 1700cc Type 4 engines. The 8mm valve stems provide durability and compatibility with original-style valvetrain components.

A key upgrade is the improved head sealing surface, which removes the requirement for the original cylinder barrel sealing rings. This modernised design improves sealing integrity between the head and cylinders, reducing the risk of compression leaks and increasing long-term reliability—particularly important on air-cooled engines operating under sustained load.

Supplied fully assembled, this cylinder head includes:

• Valves

• Valve springs

• Rocker studs

• Inlet manifold studs

• Exhaust studs

This makes it a true ready-to-install solution, saving time during engine assembly and ensuring all critical fixings are correctly matched.

If your engine build does not require EGR, the EGR ports can be securely blanked using EGR plug kit AC101033, allowing this head to be used on non-EGR setups while retaining the correct original casting style.
