340rocker oiling

If you want to see, you can remove the rocker shaft(s) and the spark plugs (so it turns over easier, then turn it with the starter a couple turns. You will have oil squirt out of the rocker pedestal but be careful, it's at the system oil pressure...lol. Ticking may be sloppy rockers on the shafts if things are worn too. Or lifter preload, or too much lifter bore clearance.
