yeah that is frustrating i know.....i tend to go old school on those..
i use either aviation gasket seal, (jar with brush) or the tube of permatex #2
the brown crap looking Goo. they both are sticky enough to hold the end seals, as far as the pan gasket goes, glue it to the pan first. then with a couple of screws started you can use an awl to shift the gasket to get the other screws in.....if your doing it alone you will have a harder time. works better with a set of hands holding the pan while you put the screws in
