Cylinder Head Single Port 1500-1600 | Bare

Cylinder head, bare / without valves, for single-port engines.
VW Beetle engines 1500 | 1600cc (single port) - up to 7/1970.
VW Type 3 engines 1500cc.

It is not always possible to rebuild your cylinder head with new valves and valve guides. On air-cooled 1300 and 1600cc dual-port engines it often happens that the cylinder head has cracks and only one option remains, namely replacement. Other air- and water-cooled cylinder heads are less prone to cracking and should only be replaced in the event of severe engine damage.

Valves and valve guides are subject to wear, so it is not advisable to reuse them during a full engine overhaul. If you have the right knowledge and tools, you can replace valve guides, valves and possibly valve seats yourself. If this is not the case, we recommend replacing the entire cylinder head.

Most cylinder heads are supplied complete with valves, valve guides, springs and, in the case of diesel engines, even with a fully fitted camshaft. This does not apply to all engines; some are available without valves and springs, but have valve guides and valve seats. With these cylinder heads it is necessary to buy the other components separately, as the valves and valve seats must be lapped together by hand or, if applicable, by machine using a lapping paste.

Note: On fully assembled cylinder heads it is always advisable to carry out a leak test before fitting the cylinder head. Although every cylinder head is tested at the factory, you should never blindly assume that this is the case; only then do you have 100% certainty. This is obvious to the professional, but many hobby users are not familiar with the subject.

Additional explanation by brand:

Paruzzi
These cylinder heads are only supplied bare; reusing springs, spring retainers and valve keepers is possible, although new parts are preferred (available separately in our shop). Never reuse your old valves.

Autolinea
These are fully assembled (complete) cylinder heads, developed over the years and now better than the original. For example, much attention was paid to improving cooling, high-quality valves, hardened valve keys and the combustion chamber with a capacity of 51.5cc. These cylinder heads are made by Autolinea in Brazil specially for EMPI, with all operations and the cylinder head filling done in the USA. In terms of quality they are the best standard cylinder heads available for dual-port Type 1 and Type 3 engines.

AMC
These high-quality cylinder heads are made in Spain, but are not yet ready to be fitted for the European market. The 1700 and 1800cc were prepared for an EGR system (exhaust gas recirculation), mainly used for the US market to meet the legal emission standards introduced from 1968. Under the exhaust valves there is an EGR opening, which must be closed if no EGR system is present (as is generally the case with Volkswagen vehicles intended for the European market). The connection is accessible from the outside and can be closed with an M10 x 1.0 blanking plug supplied as standard in the cylinder head.

WBX and diesel cylinder heads are ready to fit; diesel cylinder heads are also supplied with the camshaft.
