What this makes me wonder is: How many OLD cylinders that measure oval are to be contributed to wear? OR were they oval upon initial installation and therefore wore a little faster to be pulled and discovered to be oval. Just something to chew on for a second.

My recent set of Mahles came in a Porsche box already assembled. Would this not be how the Porsche assemblers would have recieved them? On another thread I was instructed to break them down and check everything which I'll likely do, BUT would this be done on a regular production engine? If so, how would've Porsche double checked what Mahle sent them in a mass production setting?
