Which oil pan gasket , an any tips on getting it on (340)

Hello everyone
I’m looking for an oil pan gasket not cork . I see there are a few companies that make rubber ones . Does anyone have an experience with any one being better than another ? Or one to stay away from due to quality or fitting Issues ?
This will be going on a 70 ebody I’m not sure if there’s any difference between that and a abody in that area of the car? the car is 340 4speed with manifolds . Does anyone have in words of wisdom for putting on the gasket a what problem I might get into Or anything that might make the job easier, or things not to do .
any an all information will be helpful. Thank you
