Good post mortem thoughts. I agree the 3/4 turn preload shouldn't be a deal breaker. That said though, nowadays, the conventional wisdom is to use a zinc rich break-in oil and low tension valve springs during the first 20 minutes of run time for any flat tappet. I've also heard it said that all flat tappet cams fail... just a matter of when.
Sorry to hear Dr. Jack Camorkian may have made a visit to your shop, John. You could sure use a little less grief my friend.
