Any one interested in the oiling mods I did?

just looking at your pic there I don't understand the benifit of running the line from front to rear of the block on the same lifter galley ? I have a line in mine that goes to the front in the same place but mine goes to the back of the block and out through the rear face where the intake seals between the dizzy and the oil pressure output then my return line from my oil filter( in aus we have remote filters due to steering box being there ) is split and one goes to the original inlet on the block and the other goes to the new inlet near the dizzy to oil from each end of the block

The tube on the galley has the same benefit as your setup. It is just that the tap in location is different. Your setup has the benefit of eliminating the 90 degree filter deal.
Your set up and the one I have done as well as the crossover tube all basically reverse feed the right side oil galley with the sole benefit of improved oiling to the main bearings, specifically number four main which is the most problematic because the oil tends to run right past it and not make the 90 degree turn from the galley. Reverse feeding the galley evens out the pressure and eliminates the high oil flow velocity. This was explained very well by a previous poster in this thread.
This same oil mod has been adopted right in the block casting of the newer chebby small blocks as well. I was able to restrict the oil to all five cam bearings by drilling a new smaller feed hole
In the cam bearings. When these new holes are aligned in the block this also shuts off completely all feed to the rocker arms. This also leaves more oil for the main and rod bearings.
But by doing this we need a new feed for the rockers which is what the other crossover brake line tube accomplishes( not to be confused with the oil galley cross over tube).
