Pork cooking temperature Rule #2
Internal temperature for pork, no matter how long it takes, should be 160 degrees F.

Usually if you have achieved a temperature of 155 degrees F. by the time the pork has rested and before cutting, it will be done.
Pork cooking temperature Rule #3
Buy a meat thermometer. This will save you a lot of grief. Some people will slice into pork to see if it is done. This releases liquids in the pork that make the pork more succulent. A meat thermometer makes a tiny hole so loss of moisture is greatly reduced. A meat thermometer makes estimating the time your pork will be done easier with out releasing liquids or de-facing your dinner.
