Everything I mentioned is not only legal.. but in my eyes important.. if you are going to spend the money in the machine shop.. Everything I mentioned is not of any additional cost to you, just your time. If you want to learn how to do it.. why not spend the time and do it right?

P.S. I have built engines that I have thrown together under the direction of the person that I was doing it for.. but I make it aware of the consequences from every assumption that we make.

What if the hot-tank process wedged a piece of debris into the rod oil passenges..it woudln't of been the first time I have seen it.

Since this is your first motor build I would ask around to people in your area about a good machine shop. Which can either make or break this experience.. And NEVER assume that a machine shop will do something.. always confirm. Not that I don't trust them.. it is just yout money and time... not theirs.
