Your valve springs oughtta be lovin those ramprates. 1.72's are harsh man. Why are you changing your cam? Do you plan on getting heads real soon? There really is no point in changing the cam. I'd get away from those 1.72's try to swap them with someone that wants them for 1.6's. Then I would get a TFS stage 1.
