I have a set of KB107 pistons and their website says. 001-0045 p/w clearance. My block will give me. 008. How loose can they be run?
Line2line coating is what you want.
With that much clearance you are asking a lot for a coating.. I had 1 set of pistons coated and they wouldnt guarantee any with that much.. most they would go was .004.. I ran that engine on the loose side.. it had piston slap when cold but as it heated up it would get better
