X2.....I'd also add....when the valve lash is adjusted properly, you should still have a little valve train noise, otherwise, they're probably adjusted too tight. I like doing them HOT, and engine running. Kinda hard on feeler gauges but seems more accurate to me. You'll need to do it at a real slow idle or you'll have oil splashing around. I made a cut-off set of valve covers to keep the drain-back oil from dripping over the side of the head. I know, it's an aquired taste but I do the slant 6's the same way. Just be carefull holding the 3/8 wrench while turning the adjuster!
