Those roller lifters are no longer available and it appears that Superior has switched to a new roller lifter design that incorporates off-the shelf aviation style lifter guts. At one point, a few years ago, Superior had started modifying their engine cases to allow installation of their new style roller lifter from the outside. In other words, the entire roller lifter could be removed once the pushrod tube is removed. Do you recall if your engine’s roller lifters are removable without splitting the case? I anticipate that the answer is “no”, but I’m just curious. Possibly they eventually designed a replacement lifter that didn’t require any modification to their existing engine case. I didn’t particularly like their case mod anyway.... Any input would be appreciated. Thank you!

When I was in the school I do recall them saying that i would be able to remove the lifters without splitting the case. I just checked the Superior website for confirmation.
Here is what it says:
Roller Lifters
Our roller lifters were developed to provide a smoother running engine and to help reduce wear between the camshaft lobe and the roller face, minimizing the occurrences of cam-lifter spalling.
Superior Exclusive!
A unique feature of our roller lifter design is that they can be removed without opening the engine case, which reduces costly maintenance and repairs.
Hope that helped.
