If you do, you will almost certainly crack the block under the thread holes. A clean head, skimmed, clean block, also skimmed, good gasket and a light spray both sides with Hylomar and torque to 35-45 lbs. The problem arises with an old block, rusted/corroded in the water galleries, combined with 70 year old cast iron. Things ain't what they used to be..........
