Tubing passenger side oil galley

I'm planning to use a mechanical flat-tappet cam in my 340/416 build. LA-style lubrication (not through the pushrods)

I've read every internet article, forum post, magazine article and book chapter I can get my hands on, but still a little hazy on the issue of tubing the block.

Specifically, I see it is usually discussed with roller mechanical cams/lifters; but what about flat-tappet cams? Should the driver's side galley also be tubed or just a plug inserted in the passage from the #1 main up to the galley?

Once the tubing is done, how do the tappets get lubricated?

Thanks!
