Hey it`s strange .My 66 C.S.M. says 95FT/LB. You n other references quote 80- 90.
Which is correct?
Is it to do with oil on the bolts /or not ?
Is it concerning a 7/16 or 1/2 " bolt ?
Is it not that critical ?
Pretty keen to find out b4 I let the builder loose with my C.S.M.

bolts
torque bolts in a three stage circular pattern, from the center of the head outwards. so like 30, 60, then final...add 5 lbs. if you re-use bolts. 80 lbs. sounds about right.

yeah
i even heard of dudes runnin' a flat bottom chaser tap to clean-out the threads. i've never done that, i did like you said and used compressed air to clean out the holes along with a good blast of Berrymans chemtool. never had a problem with that method and even reused head gaskets. i think olds. motors have good clamping pressure around the cylinders so maybe torque isn't so critical. i know my torgue wrench is like +/- 10% at best, on a good day, so who knows.

Thanks for all the help guys! This site really helps a lot! You can find thousands of websites and info on bowtie motors at any given time, but you really gotta dig deep in google for some reliable olds info!
