Maybe I am missing something here, if I am I will apologize in advance.

Sorry---But the failed to adjust the valves explanation just doesn't wash.
Why would anybody pay big bucks to have a engine built,dynoed & proven & then expect the builder to un-adjust (word?) the valves.
I hazzard to say that very few here that have purchased a proven "crate" engine from a respectable builder has or would expect to have to.

J.M.O.
