Any one interested in the oiling mods I did?

Hey GJ. I noticed you had your cam bearing and frost plugs in when you started the mods, how did you clean up all your metal filings you created without flushing everything out such as tanking the block, just using air? You do any cam bearing mods, do such exist? I have my block at a machine shop along with my pistons to have my 340 taken to .030" over and my Hughes stud girdle to machine the main caps plus line hone them. I asked them to hold off on cam bearings yet, but I think I should have not bothered taking anything to them yet and did all the oiling mods before the rest of the machine work. Whats your take on this, can I have them do the work and safely clean up block on my own? Or since I can still have them wait, maybe go that way. I'm building a 416"

Cheers
Rod
