Hi all. I am hoping someone can give me some good advice about new rocker arms to  suit 272-292 y block. I have replaced complete valve train during the engine rebuild and now have a problem.  The ball on the end of the rocker arm adjusting screw has worn away to about half its size and I am very suspect about the rest as a couple look like they are going down the same path.  All American made (suppossedly).  The new rocker arms, shafts. etc have done about 4-5 hours, if that in the shed.  I need advice as to what brand or type to buy this time. (no chinesium) This is not a good start for a new engine so i am suitably pissed off.  Thank you in advance.  Waiting patiently.  The pushrods came from FA products and are okay unless you know different the rockers came from another supplier.  
  

  

ted or someone might know better but i would think these screws are a cheap knockoff.the factory one dont even wear when the rockers arent getting oil.i tried to get a set of the self locking ones for a friend a couple years ago and couldnt get a set anywhere.

Is the wear on both cylinder banks or only one side? Is this possibly the oiling issue y-blocks are notorious for? You obviously need new adjusting screws, but I think I'd confirm proper oiling by spinning the oil pump while watching for oil at the rocker arms. If you get little or no oil at the rockers remove both shaft and rocker assemblies and spin the pump again to see if oil comes out of the oil passages in the heads that lead up to the rockers.

Do they all look the same? Are the rocker arm shifts assembled correctly? Did the rebuild include the revision to the center cam bearing in the block? These are questions we all ask today.

I've read good things about Crane's adjusters. It looks like Summit has them. 

Don't run them, find old used Ford parts, the rockers are good, the balls and most push rods are no good. 

hi yes plenty of clean oil..both sides are looking a bit ordinary

yes all assembled correctly and lots of clean oil

Maybe pricey but contact Manton Pushrods in Lake Elsinore California. They make pushrods and adjusting screws and list the material. under adjusting screws they show diameter of the ball and threads on their website….
 A few years ago I was advised to get the socket style adjuster and push rods without the cup style for my racing GMC 6 custom roller rockers but didn’t.

i would get an old ford set and change your oil.
