One of the go fast changes made to the T150 and T160's was to get rid of the swivel style tappet adjusters and go with Elephant Foot "Norman Hyde" solid tappet adjusters.
I'm puzzled why you'd go this way and not use these which are much lighter and an improvement on the stock adjusters. No need to mess with pushrods, no messing with the rocker arm threads. Seems to be excessive overkill using those swivel types to me unless you are expecting to be doing massive mileage!https://www.classicbritishspares.com/collections/bsa-engine/products/mushroom-tappet-adjusters
