How do I check piston to valve clearance on VVT engine in limit positions

Hello Guys,
I am checking valve to piston clearance on VVT engine and I came to a question, as I cannot figure it out myself, maybe I am too lazy, I dunno...
So obviously, without pressure in the engine, I cannot move the cam wheel actuator, but it is probably somehow possible, so I can check clearance in both fully retart and fully advanced possitions.
How do I do this ? Any tips ?
Thanks

That makes sense , so that is about 23.5°, I believe maximum for VVT actuator is what, 24 cam degrees ?
Thanks for helping me out, now I now I can add more compression in the future and still be good. Now there is 1.6mm clearance, without gasket, and I am at 11.3:1 Compression ratio with 1mm Gasket.
