And don't dip the head bolts in oil. Too much oil on the threads can puddle in the bottom of the hole and hydraulic as the bolt get's to the end of it's travel. It can crack the block. Dip your finger in the oil and brush a little on the threads.
Thanks, have done just that. Bolts were brushed, inserted, removed and wiped off to remove any excess. Don't want the oil to affect contact surface of head gasket either.
