I am by no means an expert with nitrous but i have run a 150 shot on a non nitrous cam many times with no issues. My buddy runs a 200 shot on his car with a non nitrous cam and has 0 issues (his is a sbc). I believe a nitrous cam just makes the most out of using nitrous and people generally run on when they have big shots 300+. I do not see a reason why you would have an issue with a 200 as long as it doesnt run lean and you use a good quality fuel. Make sure you ring end gaps are good and you may have to run a diffrent plug.
