    Although this does not necessarily address your oil consumption issue, I cannot believe anyone else hasn't said anything about it.

    Just to get it right in my mind, you said you used different length pushrods in your engine because the valve stems were all at different heights, is that correct? That has to be one of the most difficult and expensive band aids I've ever heard of in my life.

    You should have sent those heads back to the shop that did them and had them redo those head and get them right.

    Lastly, to your "oil consumption" issue. You're trying to chase oil consumption at 500 miles? For real? If this engine were under a factory manufacturer's warranty, they'd laugh at you and tell you to put enough miles on it to break it in, because IT'S NOT. ....and you're tearing into it to fix a problem it may well not have.

      You can either make sure the piston is up high enough in the bore to stop the valve falling in or else use some tight rubber bands around the stem. Also you can use compressed air and a cylinder hose adapter which are available cheap from Summit and use air to hold the valves up in place. (screw into the plug hole with an O ring seal)
