Anyone ever run Speedmaster Heads on their small blocks

Won't hurt anything keeping hollow pushrods and Magnum oil-through lifters if the rest of the system is solid. If you already have low oil pressure with a full Magnum head setup, this would make it a tiny bit lower pressure, maybe, but definitely not noticeable if the rest of the short block is good.
Comp Cams cast rockers (Pro Magnums maybe?) are the rockers I have for this same build plan. Found out later the PRW may also be this way. Trick Flow is calling out Harland Sharp part numbers for their LA heads on Magnum short blocks.
