Cylinder head with big valves (39.3 x 33.0) (each)

AMC
The cylinder heads of the CU and CV type 4 engines, which are only used in the Vanagon Bus, are equipped as standard with 39.3 mm intake valves. The 2-litre engines of the Bay Window Bus never exceeded 37.5 mm, while the 1700 and 1800 models were equipped with 39.3 valves. For all those working on type 4 engines, it makes sense to use these cylinder heads instead of the original with the smaller 2 mm intake valves. Also recommended for the original revision, this is an improvement over the original.
AMC cylinder heads are produced in Spain and are of very high quality. AMC with EMPI is the only manufacturer where you can mount the cylinder head directly. Nevertheless, a professional will dismantle everything to check with his own eyes and measuring devices if the cylinder head meets his wishes. We advise you to use this method of working again, when you work on the engine, you are 100% sure and leave nothing to chance.
