Checking piston to valve clearance

Starting to buy parts and narrow down what I’m looking for to do h/c/i.

I have a set of mast black label heads on the way soon and I’ll be looking for less than max effort na but still aggressive when choosing cam. (I may make another thread for suggestions on that soon)

I want good valve train reliability so I’m pretty sure I want to go with Johnson 2110 drop ins for lifters with tsp roller rockers.

Since I’ll have aftermarket heads and new lifters what’s the best way to go about checking pv clearance.

I’ve read many articles and many to most say not to use hydraulic lifters. They state to use solid. I’ve seen methods to modify ls7 Type lifters to make a solid roller for this purpose but that doesn’t seem to help unless I find the correct pushrod length for this and then buy two pushrods to check. But that seems like a lot of extra work and would it even be accurate enough.

However: I have seen one that states you could use hydraulic lifter if you’re using check springs. I’m really hoping this will work because it will allow me to set one head up and find proper PR length and then put them on the other side with check springs to check pv. Not sure if I would use clay or dial indicator method. Clay is easier but may risk compressing lifters.

Anyhow just looking for input/guidance or if someone has maybe even done it.
Thanks.
