Checking the head and deck are pretty easy. Straight edge and some feeler gauges is about all you need. Kevin's Machine down there can do that for you. I don't have the shop number (just Kevin's cell) but most any machine shop around will check it for flatness for free- Just take them the specs so they don't have to look it up.
