Every engine you have listed are good engines and will fill your needs on this plane. You will be happy with any of them. We have three at our field, one with a 3W 120, one with a ZDZ-100, one with a 3W-100. All fly great. No none of them have the same exhaust bolt pattern. I know nothing about the MVVS 116. Good luck, By the way, the GP-MC Cap flyes like a 15 pound plane on steriods. It is one nice, well built great flying plane.
