Just putting the engine back together on the Williams after a head overhaul, new head gasket and timing belt.
its on 116K miles so thought it needed a refresh.

Whats the method of bolting it down?

Torque wrench ok or do i need another tool as well?


Thank you all

you'll need an angle gauge aswell.

Is procedure in Autodata ok or is there anything else to be cautious about?

The printout you get from autodata is correct if it is the same as the one I had after my head refurb on the valver.

Bear in mind, new head bolts must be used and must be tightened precisely, i.e. done up, undone, done up to torque, then to correct degree's as specified +/- 3 degree allowance iirc. You will need a T55 Torx bit for the head bolts. I went through 3 Torx bits doing this ;) If any break on you, make sure you get the fragments out thoroughly, with magnet if you can.

Also, make sure the bolt holes have been cleaned out of all and any fluid/gunk. When it gets hot, hydraulic pressure can cause failure in the head.
