One other simple way is to Take all the Plugs out,
Use a thin rope Or heavy string.Pushing it into the plug hole.LEAVEing Some hanging out so that you can remove it.Losen The rockers SLOWLY roll the motor over by hand.Till it stops It will hold
The valves in Place. They also Make a tool to remover the springs With out removing the head.
Called a Easy Squeeze Modle #2995 I can't remember if I bought it from Snap-on Or Mac Tools
This Tool compresses The Spring Right on the head and You can remove Or in Your case reinstall the Keeper.
God doesn't like ugly.
