Update on my oil pan flattening efforts: I was successful in flattening the oil pan flanges (didn't take much force), then I used Gasgacinch on the pan side and bearing grease on the engine side. I "borrowed" some push pins from my wife's stash, and cut them in half, then pushed them through the gasket ends. I did trim the 2 end gaskets to 1/8" above the surface, as the Gaskets were over 1/2" proud on each side, which seemed too much. Easy-peasy. I then dipped the pan bolts in Locktite Red (the weakest of the brand, apparently), then torqued the to 15 ft lbs. We'll see if I get any leaks.
