When I stripped my engine down I forgot to take a note of the position and orientation or the real crank oil seal. I fitted it yesterday so that the rear surface is flush with the engine block. Does that sound about right?

Also, I assume it has the flat surface racing out to the back. Again, is that the correct way round?
 
A pic would help.

I don't know about specific V8 but if the seal is angled it needs to point in to the engine and are usually set just below flush level with the chamfer on the block.
 
If it is anything like a normal front crankshaft seal then there will probably be some form of spring holding a bit of tension around the seal when it fits around the crank. This spring side is on the inside of the engine.
 
The engine is still on the stand so hard to take a good picture but these are the best I could do.

yes
 
An engine builder showed me how to remove the spring from the seal and shorten it a few mm then refit it. It makes the seal that tighter bit fit around the crank keeping it sealed longer. Has worked for me ever since.....
