[Healeys] Head bolt torque

[Ricchardd Mayor]

The head studs do not go into any water jacket.  Do not use any sealant.  In spite of what any manual says, you should only put the studs in finger tight.

Haynes also recommends 900 inch lbs as the target.Use Locktiite white as the sealant for all studs-especially the ones which go into the water jacket! Hank
