It shouldn't matter, the holes are there to spray the cylinder walls, so specific to the cylinder they are in, left or right shouldn't matter.
But there are arguments in "V" engines for facing oil holes "inside", so Bank 1 oil holes face Bank 2 and visa versa.
But nothing "proven".
An online shop manual did say this about Ford 4.0l, " The oil hole in the connecting rod must face the RH side of the cylinder block"
But wasn't specific on 4.0l OHV or SOHC
