Based on my experience and what I have read on this board (and others - shame on me
) that is a fairly common symptom. Especially if the ones you adjusted were on the tight side of spec. Aside from the hassle of pulling it all apart it's a good idea to double check things.
I should qualify "my experience" as doing a valve adjust once under a watchful eye but the valve train was slightly "noisier" after wards while being very rythmic... I would have panicked had we not triple checked everything before buttoning it back up.
