I would recommend the MPN: SP-4002 if you are looking for something with 0 MOA and MPN: SP-4602 if you want the 20 MOA version. Spuhr also offers other MOA values for their mounts if you are interested, please email us at techsales@opticsplanet.com and we can find a different option depending on what you are looking for.
Because you already have a 20 MOA base/rail, I would recommend using a 0 MOA mount unless you wanted additional MOA. MPN:SP-4004 would be my recommendation as it will provide enough clearance for your objective lens and no additional MOA. If you want more MOA, then use model MPN:SP-4804.
The 39mm (MPN:SP-4007) Spuhr ISMS 34mm Rifle Scope Mount would provide enough clearance for your objective lens while keeping the scope as close to the receiver as possible. I would also recommend the 1.5" height NightForce Ring Set, found by using the link below:

I recommend using the 38mm or 39mm high Spuhr ISMS 34mm Rifle Scope Mount for that scope and rifle.
The correct ring height you need to mount the Vortex Strike Eagle 5-25x56 to a Remington 700 also depends on if you have a heavy barrel on that rifle. The 39mm high or 48mm high Spuhr ISMS 34mm Rifle Scope Mount should work fine. The guide located at the link below can give you some more information to help you determine what height rings you need.

I recommend using the 38mm high Spuhr ISMS 34mm Rifle Scope Mount. Now you will need to select which exact model you want based on the specific features you are looking for now that you have the height.
The Spuhr ISMS 34mm Riflescope Mount I would recommend the MPN: SP-4002 (38mm) if you are looking for something with 0 MOA and MPN: SP-4602 (38mm - 20.6 MOA) if you want the 20 MOA version. Both of these mounts translate to 1.496" in height which will allow clearance for your 56mm objective lens. I would say if you plan to engage targets past 600 meters regularly, go with the 20.6 MOA option. This will allow for more elevation adjustment at distance.

Your Nightforce optic will pair together fine with the 121mm Spuhr ISMS 34mm Riflescope Mount. Although I do not know what rifle you will be putting this scope on, I would at least suggest using extra high rings for a 56mm objective lens to allow for clearance.

Yes. The 38mm Spuhr mount is 1.496 inches high which equates to an extra high mount. Which is the correct height needed for a 56mm objective lens.
