Please don't take this personal, but seeing a post like this from a professional shop that is charging someone to rebuild their engine is pretty darn scary. It also tells me that you are likely not getting the motor put together right as there are some unique assembly processes. Comments like 'little crossbolts' are also pretty scary. Can I suggest that you take some of the money you are charging this guy and go and get a proper book? Then read it before you go any further. You will be doing yourself, your shop and your customer a favor if you follow the manual instead of trying to wing it by the seat of your pants.

My $.02 for what it's worth
