Ted ,question

What about instructions for piston , crank and rod clearances/tolerances?
In my limited experience , seems most "machine shops" get it close and usually end up at the upper end of tolerances . Sure the engine runs good , it's easier for the shop , but perhaps the longevity isn't going to be as good
Should you (for ie.) include instructions to end up with .015 clearance for the pistons etc. and what should you expect to pay extra for the shop to be a little more careful?

thanks
