M104 Oil Pan Stuck

[gsvhouston]

My 94 E320 has stripped oil plug threads in the oil pan, such that I can't tighten the plug properly, resulting in an oil leak.
First I tried to re-tap a bigger thread and use a bigger plug but it didn't work out as expected: the new thread came out slanted in relation to the sealing surface on the pan and the oil leaks continued.
Next step I decided to go all the way and change the oil pan.
I followed all the good practices for the job and now I have the engine lifted as far as it can go, the oil pan is loose, but there is no way the damn oil pan will come out.
I heard that putting cylinders 5 and 6 in top dead center will help clear the pan out.
Anyone has experience with this type of issue? Please help!
