Are these rotators?

In the end, engines built by J Seery and Ol Ron are both great runners, so if I use common sense I should be ok....... On another note this engine must have the good hollow johnson lifters in it. I had to do a LOT of wrenching on them and the tension on the bolts was very consistent and very snug. They gave me a lot of confidence that my settings were going to last. No loose ones in the batch.

I like studs for the same reason ,less wear and tear on the block threads.
On studs the wear is on the steel threads of the stud and nut instead of the softer cast iron threads of the block.
