512 B Underway

Question Ramm. 440 Source sells a long drill bit for that they recommend to drill from galley to mains for better oiling. Don't think they mention size. Do you recommend this mod along with the added small thrust hole & 1/2" pickup? I'm about to start on 400/470 build for the drag car next week and would like to cover all the small oiling mods while the block is getting prepped for me.
