Some engines will make more of a mess than others, depending on rpm, oil temp/viscosity/pressure, type of cam/lifters, style of rocker, poly locks, and valvetrain geometry to name a few variables.
The poly locks can deflect/catch oil at lower rpm that might otherwise reach the tip of the rocker if stock type adj. nuts were used, or maybe not? Just a thought. Did you rev it up? Was it hot?
Did you check valve train geometry? Does the pushrod hole come close to the hole/relief in the pushrod seat of the rocker? Can you see oil getting to the trunion?
I've seen some engines not make much of a mess, and others give you a burning hot bath without using deflectors.
If oil is getting to the trunion it should be ok IMHO.

If you want to do a clean job take a set of scrap valve covers and cut a hole over each rocker stud large enough for your adjuster, put the covers on then adjust your rockers with it running.

It will also depend on if the motor has oil restrictors also, this will limit the amount of oil to the top end.
