Pan gasket for 360. What one works best?

How about the rear cam seal, mine leaked on the 340 I had. I pulled out the old soft plug, cleaned out the reciever in the block and replaced it with a new one with some permatex around the edges. It would run down the back of the block and I swear it looked like the rear main seal leaking. I had to pull the trans and flywheel to get at it..PITA
