360 oiling system questions?

[68gtx]

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?

That's incorrect. The Magnum engines oil through the lifters and pushrods. They began in 1992. Yours is still the standard LA. To be certain, it does have shaft mounted rockers, right? If so, it oils through the block and heads into the rocker shafts.

well it has edelbrock heads on it part number 60775, edelbrock instructions say that they fit 67 to 91 360's, the block is a factory roller cam block, block does have the oil passage to provide oil to the heads and rocker shafts.. it has solid pushrods and adjustable roller shaft mount rockers as well..i was told this is a magnum block and this cannot work,. i just bought this truck and it has prob several thousand miles on it, if the lifters were not getting oil or the pushrods , rockers , wouldnt something have failed or wouldnt there be signs of oil starvation???

It's not a Magnum block. It's an LA roller block.
