A) measure the clearance

If the bore is too large:
B) get another block bored and send the pistons with it
C) get bigger pistons and have it rebored

boring blindly

slim chance in hell that the machine shop met the clearance specs without having the pistons handy. I dont understand why a shop would even bore a block without knowing what it needed to go out to.

but yea, good advice on measuring the clearance. I'll add that to your options

You're going to need to know how much clearance Wiseco recommends to know if you meet spec. They should be a bit looser than stock anyway, as forged pistons expand more than oem cast-type pistons. Get you're specs, then measure. If you are within specs, good. If the bores are too big, then you'll need new pistons and a new bore/hone. If it's too small...that's not as bad, because you'll just need a new bore/hone.
