On the off-chance that you put your cam plug in the same way that you put your freeze plug in (which is the
wrong way to put a cam plug in an FE) you should check a couple of other things just to be safe. If you put the cam plug in the wrong way it can push the cam forward on to the the thrust plate, so check for wear. The plug itself gets chewed which can cause crap to go down the galley in to the rod bearings (usually #8). If you did put the cam plug in backwards (and KC & Barry will tell you that
does happen all the time) you really should check a little further to make sure you don't have additional problems waiting for you.
