Thanks all for the advice.
Sorry to not reply earlier, but couldn't get back online in NC. Thankfully, I'm back in Vermont --it hell out there.
My advice from this learning experience is to not try to adjust the valves after a sleepless night of travel.
The car was not in neutral. I figured this out shortly after my post.
Just goes to show that you can make a foolish mistake even if you have done something before. Needless to say I checked the clearances three times before putting the valve cover back on.
