My take on the oiling system crossover tube for the small block

This is a combination of my thoughts and ideas taken from the Guitar Jones oiling system modifications thread.
If you have some input that would help along these lines and to clarify some of the thinking you're more than welcome to post but if you think that you just need to post negative don't bother I'm not interested.
Does anyone here know where to get the discontinued right lifter galley restriction pipe kit that Mancini used to sell? I have the drills but no swedge. Thank you.
