John Mason.

Perhaps John, it is worth noting that Chris specifically says "re-torque" not tighten. i.e. restore to previous settings the tension originally set in the retaining studs after the head has settled. To do this correctly the engine would need to be cold , as it was when the head was originally torqued down??
