Hi Brian,
OM and I posted the 1970's specs on your other thread yesterday.

Late D8H Head Torque
Hi Brian,
below are specs dated Feb 70.
The thread lubricant mentioned in the chart is critical to achieving correct stud stretch/clamping force, to help clamp the head firmly and prevent gasket etc. failures.
Hope this helps.
Cheers,

I assume that you don't have a field instalation that converted the counter bore block to a spacerplate one.Your serial number is rather high and I have seen high serial numbered H'S with the spacer plate block. Different torque specs are used for the later blocks.
