Car dropped 250 RPM and is now stuttering

Yes it may be, the mixture screws will have to be adjusted in compensation. And 650/700 for that cam is kindof a stretch.

Good point about the mixture screws. Forgot that I had moved those out messing around. I will see if I can get the gauge to steady up.

Regarding your comment on 650/700 is a stretch for the cam. What do you mean by this?

Which pcv did you get?

Equivalent of a Fram FV191. Supposedly this one works with lower vacuums around 11.
