Combustion Chamber P&P

 

    My goal for the combustion chambers for my 1776cc project engine was to simply smooth them.  If I were planning to build a huge HP motor, I would look into and research the reshaping of the combustion chambers, un-shrouding the valves, relocating sparkplugs, etc, etc.   That's a little much for my mild power plant.

    The above photos show my stock "040" heads in their "un-molested" state.  Note the rough texture of the combustion chambers.

    Now they're nice and smooth.  I was pretty pleased with how these turned out though I wish I had all the tools necessary to really finish them with a good polishing.
