Can I use rigid foam inside and outside a concrete block wall?

I have a concrete block barn I am converting to a living space. I plan to use Insofast 2″ EPS panels on the interior which with the block gives me R-12 (Block at 3 and foam at 9). I would like to get a better R value, by adding foam to the outside. Would this create a moisture trapping problem?
How would I fasten the furring strips through the foam and into the block? I was thinking Tapcon screws.
