An over rev on the over run can do lots of bad things, but not likely to cause issue with cam timing. Easy enough to check though by removing the front cover and rotating the engine by hand (or rocking the machine when in a higher gear) to see if the marks line up (see the S&S manual).
You mentioned revs went "to the max/limit" briefly. As a reminder, the ECU rev limiter will not/does not work on a 'mechanical' vehicle speed induced over rev such as you would have experienced. You may have gone well past any sort of safe limit for any number of engine parts.
