VVT & +1mm Valves with Tomei 252 10.80 Cam - Will intake valves hit the exhaust valve

Hi,
With +1mm valves on the intake and exhaust, VVT, and Tomei 252 duration 10.8mm lift (intake) & 256 duration 10.0mm lift (exhaust) camshafts is there a possible issue with the intake valves hitting the exhaust valves as the VVT varies the intake cam?
I've searched and can't seem to find a definative or consitent answer. I feel like this was a pretty poular combo 5 or 6 years ago and the miataverse must know the answer!? Or perhaps it's not an issue? I've founf the odd post talking about limiting VVT travel but those cases seemed to be for piston to valve, not valve to valve which I am asking about.
Also while I have your attention, any potential issues controlling the VVT using MS3 Pro Pnp?
Cheers
