m-haddad is correct, you can modify the ACL without locking you out because these are 'add only ACL'.
There is a technique however that I would like to share with you and can be useful in many situations when you risk locking you out because a configuration mistake.
Schedule a reload like in 10 minutes with "reload in ..". If everything goes well, cancel the reload and save the configuration. If it doesn't, well just wait for the router to reboot with the pre-changes configuration.
