Default Acceptable CVO 110 piston clearance

About to start a modified CVO 110 build on a 04 RK. I am using stock HD (Mahle) pistons and stock HD cylinders that were supplied in the 110 upgrade kit. Mahle's website recommends .001" piston to wall clearance measured at 10mm from bottom of skirt. I had an independent tech to torqueplate and check this clearance for me and they are as follows: Both pistons measured exactly the same. However one cyl measured for .001-.0014 clearance and the other cyl measured for .001 -.0018 clearance. Difference was in taper, not out of round. My tech said he would run them, putting the cyl with more clearance on the rear as it tends to to run hotter.That makes sense to me. Is this additional piston clearance and cyl taper enough to cause piston noise, pre-mature wear, oil consumption etc? (preferrably looking for imput from techs who have actually checked these factory CVO 110 clearances prior to install as well as opinions which is all my tech can provide me)
