Here is a nifty chart & pic I found that shows the bolt locations, bolt sizes & length, and the torque specs for every bolt in the Timing Cover & Water Pump. This applies to 20R's, 22R's and 22RE's. Due to differences in lengths of bolts used & where they are supposed to go, I found this very helpful in getting everything back where it belonged when installing a timing chain set. I know the chart is labeled 1985-1995 but I have verified that the torque specs are correct for earlier (pre-'85) engines including 20R's.

 

That's some good info, thanks for sharing
