Ignore the specs on the JE insert. You don't want to know how much grief those specs have caused over the years. Ideally, if using a Goetze ring (factory), then you should run the factory recommended ring gaps. In some cases, the rings out of the box have a larger gap than the Porsche spec, so there's nothing you can do, but when they are nice and tight (or even better file-to-fit), you can run them as the factory intended.

If you want to convince yourself about the ring gap, put the cylinders in the freezer and then pop in the ring. You'll see that even cold, you'll probably have .005-.006" ring end gap. Likewise, when hot, you can drive a bus through the ring gap (not really, but you get the picture).

Even more confusing, some rings actually expand more than the Goetze rings so we've found that different ring materials sometimes can run tighter or looser ring gaps than the OE rings. At the end of the day, you can be secure with EBS's recommendation.
