I have the new piston’s now, nice and shiny. First job is to file the rings so the gab is about 0.02″ That might be a big job, 15 rings to do. Checking to see if they fit while I go.
Not a lot else to say, just nice and interesting.
Above you see two angled surfaces to keep the clearance for the valves, and the round cutouts, for the spark plugs and a channel to create a flame front that go’s on an angle creating a flame front that swirls, better combustion !
