DEAL WITH A QUALITY MACHINE SHOP with a GREAT REPUTATION that depends on maintaining good customer feed back for repeat work.
a competent and experienced machine shop, machinist, you can trust to point out whats REQUIRED and what is SUGGESTED is a very valuable asset , you really should look for and researching what you think needs to be done, how that is accomplished and why its likely necessary in any particular application, goes a long way toward preventing both disagreements and wasted money on an engine build AS does having access too or better yet owning some precision measuring tools that allow you to check and verify that any machine work you pay for was in fact correctly done!
