Any one interested in the oiling mods I did?

There is conflicting info in this thread about where the #1 main bearing feed is plugged. Using the crossover line with hydraulic lifters do you plug the passenger side feed, drill out the driver side to 5/16 and plug the cam feed an drill it 1/8in.
This is the way I thought it was done in the 70s.


Or do you block the left lifter galley feed from the #1 main and drill out the right side passage to 5/16 and plug the cam feed with a 1/8 hole plug. Then the cross over is just feeding the lifters.
