Back in the day, I knew my way around a Chevy smallblock pretty well. It's the only engine I've ever worked on. The curiosity is killing me, so I want to pop my valve cover off and take a look at the lobes. Is there anything I should know before doing this that is more complex than just undoing the bolts, popping the damned thing off and taking a peek? I know there are engine numbers both above and below mine that have the cam issue, and I need to know if I'm screwed or not. Thanks.
