Auto Linea 041 is a so-called plug and play cylinder head, the advantageis that you can determine which valves, valve springs, etc. are mounted. The finish of Auto Linea 041 is certainly a lot better than their standard cylinder heads. You will have to change several things if you want it to be perfect, this could include making the combustion chamber the same size(gauging), the grinding of the valves and possibly the finishing of exhaust ports. It may sound odd to perform extra work on new cylinder heads but the largest target group are probably the professionals who do not turn their hand to do some adjustments and this way Auto Linea can keep a low price. If you want a cylinder head which can be mounted directly, there are only two brands, Mofoco for Type 1, Type 3 and CT / CZ engines and AMC for Type 4, WBX and diesel engines but have not always the desired valve occupation or suitable for your displacement.

Valve size: intake: 39 mm / exhaust: 35,5 mm

The Auto Linea 041 is provided with more material between the spark plug and valves in order to avoid the well-known cracks between the valve and spark plug hole thus should spark plugs, so-called long shaft be mounted. You can choose from Bosch and NGK NGK which are available in various degrees of heat.
