Its always best to use just a little RTV when you put your oil pan on , right where the 2 ends are , it even mentions that in the instruction sheet that comes with the brand new pans like what i put on when I was putting my engine back together.I have had no leaks on my engine from there at all.the only leaking spots I had were when I had put the rear main seal on backwards <img src="/forums/images/graemlins/scared.gif" alt="" /> , so had to fix that , and the other spot was with my remote oil adapter , I had to use a bunch of RTV around all the fitting connections , and since then no more oil leakage at all.

I have since put 12,000 KM on my truck since i built it up , and no problems , other than my loss of power one that I still can't figure out , but am sure its electrical.

If you do redo your oil pan , do use a little RTV just around the 2 ends , and not a ton of it , just like a small 1/4" bead and you shouldn't have to worry about oil leaks from there unless you crank the gasket too tight and squish it.
