Great clean (inside) engine!
How many miles?
What are the "before "clearances"?
Brand of oil used and change interval?
Underside of valve cover picture (sorry, too late)
Have always changed the oil 3-4k miles. Have used wally mart full syn. 0/20 and honda oil filters. It surely did quite the morning startup down : ^ )
still at 30mpg around town, but hiway mpg is better.
4next trip I take ill have a large cargo basket on top so I'll see what that takes away from the milage.

Semantics, but: Rockers.
Lifters are part of push-rod engine design, which puts the cam shaft next to the crankshaft in the engine block (generally associated with American V8s and industrial equipment). The lifters are sort of plunger-like devices with a roller on one end which rides on a camshaft lobe. The cam lobe pushes up on the lifter, the lifter pushes the push-rod, the push rod (which extends into the cylinder head) pushes the rocker which turns the up-push into a down-push on the valve stem. Most lifters are hydraulic self-adjusting type, which eliminates the need for valve lash adjustments (aka just "valve adjustment"), which is nice.
Modern engine designs are over-head cam, where the camshaft is in the head. In an OHC design, the cam lobe pushes the rocker, which pushes down on the valve stem. Or, a "bucket" with adjustment shims in it is placed over the valve stem and valve spring, and the cam lobe presses down the bucket and valve stem directly. This greatly simplified valve train has the trade-off of needing a much longer chain or belt (timing chain / belt) between the crank and cam shaft(s). Self-adjusting OHC head designs are also a thing, though less common than hydraulic lifters in push-rod engines.
