Lift engine enough so that pan will drop out without having to twist it around.
Examine the pan flanges and straighten it at the bolt holes by laying the pan flange gasket side up on a narrow board edge, and LIGHTLY hammer the hole areas flat with the rest of the flange with a small ball peen hammer.
Clean the surfaces squeaky clean; finish off with some brake cleaner on a clean rag and wipe down to get it oil free.
Use a skim coat of Black RTV..... NOT gobs and gobs... on the block flange as a way to make the gaskets adhere to the block. Press gaskets evenly in place.
DO put gobs at the corners where the side gaskets go under the end rubber gaskets.
Skim coat on the pan flanges and put it up slowly and evenly in place
Hold the pan with one hand and start 4 corner bolts
Then put in all bolts and lightly snug them up evenly. I go every 3rd bolt or so and go around and around gradually and evenly.
When they are all snugged, then snug some more with light torque and don't distort the pan edge.
Once the gasket starts to squeeze out right beside each bolt JUST THE LEAST LITTLE BIT, THEN STOP!
