Lifters; Crower vs. Erson?

I plan to put the pan on with 4 bolts and shaft prime the pump again to watch the lifters spin also while checking valve clearance (modeling clay in valve reliefs)
Also to check oiling again.
3 birds 1 stone.
I already locktighted/torqued the timing set otherwise I would turn the cam by hand. I missed that easier process but can do while checking valve clearance.
It’s just something I ended up doing with the block on the stand, sliding a cam in to make sure it rotates good (after new bearings installed) and figured what the heck. Drop the lifters in and see that they rotate, maybe catch an issue before too much top end assembly. I’ve yet to have them spin initially just by doing that, and after assembly to then have any not spin. Not to say it wouldn’t happen. It’s all good.
