You need a 10mm wrench, flat tip screwdriver, feeler guages, and just rotate each cylinder either with the key with the coil disconnected from the distributor, or a socket on the crank to get each cylinder to top dead center, where you can set your valve lashes to factory specs. Just take off the valve cover, look around, and it will make sense. Also be sure to go easy on the valve cover nuts when putting it back on, a little tight is ok, too tight is snapping stuff off, go just tight enough to not be able to spin it back off by finger.
