I take a toothpick and place a little black Moly Chasis grease under the covers after adjusting the valves. That looks like what Saito uses when they put the engines together.
The lubrication is needed between the moving parts. Grease on the outside of these junctures can block oil from getting between the parts, where it is needed. Grease should not be applied simply by slathering it on. If there is no grease nipple installed to forcefully direct the grease between the moving parts, it should not be used.
