I think oil is flowing diagonally, and the hole is the same. Trim the gasket, but what I did was like Smitty did.

Use a better material. The material they provide is for [censored]. You can buy stuff by the roll at the auto parts stores. Just make sure it's for oil applications. and cut out your profile.

Believe me, the material they provide is really bad. I had to redo it with the better material, and a tip from a pro... skim coat the gasket material and let it stand until the outer surface is dry. This will give you a soft sealing surface and a better seal. It will also help keep things in place as your trying to put it back together.

Good luck.
