Good Idea........BUT
IMO taking the check valve stuff out would improve flow by reducing turbulence at the bolt. I went to the other site and read the 3 pages of brainstorming. I guess if you take the current banjo bolt, remove the check valve stuff, find a drill press and drill out the inlet and outlet holes, you have accomplished the same thing as buying different bolts. The only problem I see is care needs to be taken not to drill the holes too big because, if I remember right, those bolts have to be quite tight to prevent leaks. Don't want to ring them off. I guess I'll buy a set of OEM bolts and do another science project. God I love a 6.0!!!!!!

Single alternator, 20 minutes, Dual Alts. and hour, the bracket's for the second alt. needs to be removed and it's straightforward but it does take longer.

Yes I have a write up, if you follow the link to PS.org it goes over the process with pictures... If you have a single alt. system you can follow the two fuel lines off the secondary bowl and see exactly where they route too. Both IC tubes must come off, but from there it is visible.
As for the purpose of the check valve, it was to regulate pressure on either side of the head during high flow applications. The secondary fuel bowl is where the fuel is regulated and one property of fluid flow is that it will flow down the path or least resistance therefore if there is low pressure in one side of the head the flow will naturally flow in that direction. I have asked around on here and PS.org and after seeing the hole in the check valve itself there is really no explanation for the check valve. The initial thought was that it prevented backflow when the motor was shut off, but after inspection that is not the case. The fuel pump starts on key-on so you will have fuel pressure almost instantly. On a no flow situation, the check valve has a hole in it and will alleviate pressure within a few seconds.
