I had a '57 272 way back then, and had the restricted oil passage up thru the heads to the rocker shaft supports. Being the "hope to find a better way" person I am, I pulled the rocker shafts, carefully drilled the hole just large and shallow enough to accomodate a small Zerk fitting and forced chassis grease back down thru the channels. It took a while for the grease to get hot enough to allow oil flow, but I never had another problem with it. I loved that old engine. I traded it on a '59 . it had a ton of miles on it and still ran quite well. I was told that the drill and tap chips would ruin the whole thing, but magnets are great things.

I haven't got to the valve adjustment yet but when I do I will make sure its at operating temp. The process of adjusting when the engine is running still seems a little intimidating.

Not a problem with valve adjustment. Get the guage in and square to the top of the stem, apply torque with socket wrench in the other hand, there will be sufficient resistance with the adjuster nut, but it is self locking, so don't be bashful. It is more of a trick keepimg the socket on the adjuster. But it all works out OK.
Good luck

Years ago when Y-Blocks were current there were all kinds of top oiling problems and many scheams to fix them. I used a very simple and effective method. First remove the rocker assembly on one side of the engine and take out the pushrods (keep them in order). Screw a self threading grease fitting into the oil passage in the cylinder head. With a grease gun, force grease down the hole until you feel the pressure release (that is when you clear the plugged passage). Now start the engine and let it run on one bank until the grease comes back up the passage and it is followed by oil running freely. Replace the push rods and the rocker assembly and run the engine to check for free running oil at all the rockers. Now do the other side (if that is also plugged). Simple solution and you don't have to mess up the engine compartment with a mess of external oiling tubes. I performed this fix many times and it always worked.
