Sorry for the late response...I've been hibernating.

A good dial indicator will set anyone back more than a few bucks, so I 
wouldn't recommend the use (or purchase) of one to those other than 
reallllly serious shadetree mechanics. To check the lobes on the number 
one cylinder does not require the removal of the valve cover, just pull 
the oil cap off and use a flashlight. I won't elaborate on the 
appropriate position of the lobes because this is an advanced topic and 
because usually (or so one would hope) the timing marks won't be out of 
whack (or very far out of whack) with each other.
