Finally had the time to modify my valve compression tool & use it to reinstall the valves & the keepers.  The keepers are the hard part.  Always wear safety goggles when doing this.  The springs can uncompress quickly when the tool slips & you’ll get a socket, keeper, spring, or something in the face at a high velocity.  Despite 4 or 5 spring incidents I was only hit in the face twice – once in the lip with a socket and once between the eyes (but on the safety goggles) with the valve cap.

Note the tool is the same 8-inch c-clamp from harborfreight – just cut a piece of 3/4″ pvc conduit to a useable length, cut out a section (pipe cutting tool & huge pliers to break it off).  This works like a charm.  The pvc is a little flexible but that helped in my case to spread the load & not scratch the aluminum engine block and the hole I made in it is much easier to work with.

Started cleaning the valves the other day, then googled & found a youtube on how to do a better job of it with a power drill and some fine grit sand paper.  Note the difference, before on left, after on right.  After getting the build-up off you can see the pitting that’s occurred on the valve.  Also noted the inlet valves are slighting larger in diameter than the outlet valves.
