360 oiling sytem help?

have some questions about the oiling system , on a 360 , say comparing a 1980 block and a 1991 block , does the oil follow the same path? i have adjustable rockers and solid pushrods on my truck motor, which is a 1991 360 roller block , ,i think the older smallblock the oil flowed up into the rocker shafts and out onto the rockers , someone told me the rockers on this motor get lubed from the lifters to the pushrods so i cant run the solids? is this true? is there a difference?have read alot of differing info on this, the truck has a 91 bottom end with edelbrock performer heads which use adjustabel rockers, shaft mount, i have read that 92 up engine were the magnum engine which the oil flows up through the pushrods to the rockers and pre magnum was fromthe top down , but have also read that if you want to use old style heads on a newer block there is a boss you can drill out to give the oil flow to the rockers, anyone know about this enough to shed some lite on my issue?
The roller 360 blocks oil system is the same as the earlier years. Yes the rocker arm sockets are oiled by the pushrods as the rocker arms in those years have no splash oil hole on top of the pushrod socket. They also oil up through the deck and to the rocker stands like any LA motor. The oil holes running down from the pass. side galley to the mains are also up sized.
