While this table provides the value, it doesn't provide the torque pattern. You really need to get a 1973 Chassis Service Manual if you plan to work on the car like this. At this moment there are several on ebay with the least expensive one currently at $10.99.

 

Thanks

 

Note the ** for bolts requiring oil during installation. Although it calls out dipping, lightly oiling the friction contact surfaces with a brush (under the bolt head and threads) works fine. Make sure all bolts and holes are cleaned and threads chased for proper torque clamping. Most gasket fails are due to improper cleaning and torquing procedures.
