Oil pan gasket tips?

It's not easy.
Get everything clean, block, pan, timing cover, bolts.
Make sure you can get to everything easily as possible.
Blocks under the motor mounts will help.
Straighten all the sheet metal parts.
Clean the oil pickup to make sure it's clear of junk.
Change the real main if it needs it.
Good silicon sealer and a good gasket set.
Don't be in a rush.
And you won't want to do it twice!

Last, I agree with Rusty.
