Roller LA cam into Magnum?

I thought the Roller cam LA and the Magnum had different oiling holes in the cam itself since they don't oil the same. Look in a Comp Cam book or a Lunati book and the Roller cam LA cam and the Magnum cams have different part numbers, So-I don't think they are interchangeable. Tell me if I'm wrong.
LA camshaft and cam bearings have oiling holes to send oil up to the rocker shafts to oil the rocker arms.
Most Magnum camshaft and cam bearings do not have the oiling holes because they oil the rocker arms through the lifters and pushrods.
You can put an LA cam into a Magnum engine and it won’t cause any oiling issues.
