Always fit a new cylinder head gasket, and make sure all the holes line up properly. Smear a film of non-setting type gasket cement on both sides and carefully lower the gasket over the studs, taking care not to bend it. Lower the head over the studs and fit the nuts with plain washers, screwing them down finger tight.
The following procedures are to be used for tightening the nuts:
