"The instructions bondo gave are for hydraulic lifters. There are clips you can buy that keep oil from going everywhere, btw.

Unless you've had it appart, I would ask "why" they need adjustment though."

The correct way to do it is to remove the covers and leave engine off. Turn the engine until the cylinder you want to adjust is at top dead center(both valves closed). Then you tighten both valves down to specs(see manual) and loosen them a certain amount of turns. Then repeat for each cylinder.
