Will these pushrods work?

More Information for MELLING MPR381



I need to buy new pushrods as I have lost the original ones from my 1990/91 360
I am putting a set of 1974 360 heads on it.
The block has the oil galleys for the rocker shaft.
But these push rods are drilled.
I have a few thoughts running through the old noggin.
Do roller lifters require drilled pushrods? and where does the oil go when it runs into a dead end, at the rocker shaft?
Also will there be a drop in oil pressure if I use drilled pushrods?
I am thinking these are stupid questions as the block does have oil galleys for the rocker shafts anyway. With the amount of $$$ I have sunk into this I guess I'm looking for a little reassurance.

PS in regards to date stamps on the block mine is 3 10 90 Is that March 10 1990 or 10th of October 1990 in which case it'd most likely be a 1991 block?
