so with stock ls1 lifters the hole is either up or down. I installed mine with holes facing down. Is this correct?
I'm in the same boat right now. The way I see it, the lifter tray will only allow them to be installed one of two ways. Holes up or holes down. Down seems to be the right way. Can anyone verify?

It makes no difference, the entire lifter bore is pressurized with oil under operation.
