Engine bolt torque

Hey everybody! Finished the resto on the bronco body! But mow it seems many of my engine and tranny seals are leaking. I heard there is a 50 year warranty on them and itís only been 49. Just kidding. I was wondering if anyone knows the torque requirements for fastening certain items.
I have a 1968 289
What torque is needed to tighten:

1- crankshaft bearing cover
2 - oil pan
3 - water pump
4 - timing chain cover

Thanks in advance everyone for your help! Happy motoring.

Tightening the bolts won't affect the leaking seals, but the torques didn't change much (if any) over the years. Most are in this caption:



Is it coolant or oil leaking from the timing cover? Did you resurface it?

the water channels in the timing cover eroded enough to be like a hair of aluminum left. I found a replacement cover and machined the face front and back. I had oil leaking up through the timing chain cover and would pool right underneath the distributor.
I'm doing all the seals and gaskets at the moment and the timing chain and gears too. The upper main seal is gonna be the toughie without dropping the engine. But seems like it can be done!
Thanks guys!

Oil does not leak up. It's coming from the distributor, or the intake end seals, or the valve covers, and running down onto the timing cover.
