Blueprint short block

My understanding is AMC lifters and pushrods will only oil pedestal (magnum) type rockers in stock form, not LA heads/shafts. Oil will make it up the pushrod & lube the pushrod/rocker cup, but stops there. Does not get pressurized oil to the Rocker/Shaft interface, nor cool the springs. Must do the rear oiling mod, or have the block drilled (iffy proposition from what I've read) or wait for & pay for the rockers that Harland Sharp is making to go with the new Trick Flow heads that are supposedly coming out.
Someone please correct me if I'm wrong, I don't want to spread mis-information, oh, that and I will be going down these same paths in the not too distant future and want to get it right.
