262/268 cam base circle query

Tried comp cams spec sheet on website without luck.
i have just changed from comp cams XE266 cam to XE268. Just broke it in last night.
It occured to me that i might have to make pushrod/rocker adjustments if the base circles were different. Anyone able to advise? I havent road tested the motor yet, just thought I should enquire.
