Tony,
It looks like you've got the rpm performer intake just like I do. The way I got all the air out was to loosen the fitting for the water temp sender. To me, that's the highest point, and by doing so it seemed to get all the air out. I also did the hole in the thermostat too.

Edit: Just to clarify a little. The expansion tank is the highest point. But, between the temp sender location and thermostat, the temp sender location is higher. And will trap air.
