If the builder is any good, the sizes should all be checked anyway, inc the rods big ends for ovalty, make sure the block if being bored is done with a deck plate, if not go elsewhere.
I used ACL, nothing fancy in my engine, but every aspect of block was checked even for straightness, crank run on bearings etc.
Pay a little extra and get the mega heavy f/wheel lightened at the same time, you'll be glad you did when you drive it.
Why you not doing it yourself ?
