New AA 500 cylinder head in 40 x 35.5mm for Beetle / Combi engines.


The cylinder head is composed of 40mm stainless steel intake valves, and 35.5mm exhaust valves that allow circulation with 95 unleaded and 98 unleaded fuel.


The head has chromoly valve springs retainers and simple reinforced springs, perfect for small preparations.


Manufactured from the AA 500 Series in standard size (85.5mm), the air passages have been optimized in the cylinder head to promote cooling. The ducts around the intake valve have been improved to improve flow inside the cylinder head and to optimize the assembly, the combustion chamber has been redesigned and modernized, to increase the performance and power of your engine.


Another advantage of this cylinder head is its reliability, the spark plugs have long necks to minimize the risk of cracks between the valves and the spark plug housings.


AA Performance has also modified the base where the rocker arm ramp is housed to limit possible oil leaks (by eliminating the O-ring housing).


For more information: the volume of the cylinder head at its origin is approximately 60cc.


Optionally: this cylinder head can be machined to obtain the chamber volume you need (depending on your engine configuration).


Long neck stock: 12 x 125
