70 Still getting hot, what else to look for?

I have a pretty mild setup that still seems to be getting hot. Stockish 360, probably about 10:1 compression, mild cam (Comp XE 268 IIRC), J heads with stock valves and an old Edelbrock single plane. I have a home made shroud that covers the fan blades and will suck a shop towel up against the grill, a Summit 2 row aluminum rad, a flex-a-lite 18" fan and thermo clutch. Everything has about 2-300 miles on it. Yesterday with an ambient of about 80 degrees the car almost hit 210 (idling in front of my shop), which is way too hot considering the 180 stat I have in it. The intake seeps a little bit of coolant around the stat housing do to being warped, its not bad, but you can see the staining on the intake. I was wondering also if it would be a good idea to switch to a recirculating system over the puke can setup I have now, as the top few rows of the rad are never covered in coolant. I was afraid I had popped a head on my trip to the track cause the car hit about 240 in traffic, but I checked the oil and it looks brand new, no chocolate milk. Any ideas?
