I wouldn't let this guy within 20 feet of my car. Engine in it or not. I'm nothing more than a "shady tree mechanic" but even I know that pushrod length is kind of important. There's no guessing. You can't "take up" any kind of distance with the adjustable rockers. The adjustment is so small it's there for adjustments that are in thousandths of an inch. AKA valve lash. And the fact that he "was guessing" at valve lash is just incredible. How does he even work with motors? The other guys haven't kicked him out of the shop by now?
