There's no real need to pull the rockers- - - -there are two shafts that plug into a central piece called an "oil connector" and the whole assembly requires about four hands to reinstall. Just to do the shock check for carbon deposits, a few licks on top of the rocker arm tip right over the valve stem won't hurt anything. Just be careful not to get the pushrod out of alignment with the adjuster. If you don't see much change in the leak, you'll probably need to pull the head, but try the hot water trick anyway. No cost involved, and there's not really any way to do any damage.
