340 head torque requirements
Back in the very early 1970s I had a '69 340 Swinger that needed a head gasket change. I will always remember that the stock head bolt torque requirement was 95 lbs.
Why do I remember? Because the only way to get to one of the bolts on the rear of the driver-side head was with a 'wobbly-joint' Craftsman socket (we didn't want to have to move the brake master cylinder) and it wouldn't go past 92 lbs. without breaking through the wall of the socket. My buddy and I broke two of them within an hours time.
We took the first broken 'wobbly-joint' to the local Sears store and got the free replacement. We sure got a funny look from the same sales guy when we took the second broken one back an hour later.
We ended up leaving that last head bolt at 92 lbs.
