• Valves with stem 5 mm stem and 28 mm top (intake) and 24.5 mm (exhaust) head. The intake valve heads

have a layer of Eatonite to give them dimensional stability.

The cylinder head is one-piece and made of aluminum alloy.

The four valves per cylinder are fitted in the guides and are operated by two camshafts by means of

hydraulic tappets.

The valve guides are driven into the relative cylinder head seats by interference.

A special reamer is used to produce the correct bore after fitting.

The gasket between cylinder head and block is multi-layer metal type and is supplied by Spare Parts in three

different thicknesses.
