Buy the pistons and give the pistons with the block to the machine shop. That way they will know what to do. Otherwise, you take your chances.

Just make sure they give you at least 5 thousands clearance.

Most piston manufacturers will give you the recommended piston to wall clearence with the new pistons.that varies by manufacturer based on the expansion rate of their product.
