You remove the "galley" plug and then drill out the passage that runs along the bottom of the cap from front to rear. Use a 3/8" drill.
I will add some photos to my previous post late tonight of the process.
Good Day!

If increasing the oil return tube increases the oil flow, is it a good idea to also replace the stock oil pump with a high flow oil pump that some of the suppliers sell or modify the stock one?

ok I see I think now drill out the length ways passage aswell to a larger size ive not had an A apart yet so thanks this helps lots. is that a lead or babbet cap that goes back on the end?
 
Save the plug when you remove it; they can be re-used. If it is a loose fit, place the plug on an anvil and strike it with a hammer. The strike will flatten it and expand it at the same time.

New plugs are available at some suppliers. Snyder's has them.
A-6327-PL $1.00 / ea.
