I was originally asking about conrods and flywheel. The head came into play on Docs' reply but it was also a concern since I'm torquing that too. I did the search before posting, but I found nothing about the number of times you perform the cycle, which was question of the thread. I thought the book was vague on the subject. However I have to remember that these manuals are designed for trained techs with experience already. Plus, I don't think I truly understand American English translated from German!:p :
