It's totally different between VVT and non-VVT, like shown above. The best way to handle it is to pony up and spend the money on a custom cam core....$1000 ball park. I made an adapter like shown above from Nutter Racing and it's hanging on my wall. Do not like it at all, just hanging off the front. I looked at making an adapter that would include the whole journal instead of just the front only but the wall thickness of the adapter would be too thin in that it would probably crack when being heat treated or being pressed on to the cam.
Again, the best way to remedy this if you are going to use a VVT block and not use the VVT features, is to have a custom core made. That's what I did.
Unfortunately, the current cores available for the VVT blocks are only capable of handling cam specs that are compatible for use with the VVT and computer features. Who does these custom vvt cam cores.

Would it be possible (or has anyone tried) to manually control the solenoid so you can set your ICL on the fly? Advance it for bottom end and retard it for top end? (Or whatever works best for your combo)

With a large cam piston to valve clearance might be a problem. I believe the Megasquirt 3 goldbox platform supports VVT for the G3. I know megasquirt is capable of VVT control on lots of other cars.
