Why do These Cylinder heads Never show up for Sale??

Hi everyone, For magnum engines (if you don't drill the hole in the block for LA oiling) there is limited cylinder heads available that are worth the price.

While others have already covered the ability to oil through the pushrods or via the shaft bolt, many early Magnum blocks (pre-1995 in my experience at the pick-a-part), still have the head oiling provision. I have a 1994 dated 360 block with it. Food for thought.
