I had such a cooling problem it wasn't funny...I actually overheated at the beginning of DVSFII !! To test your flow, I'd remove the thermostat (temporary)...it's there to give you a "Minimum" temperature in the block...not a max. If your problem goest away, you've got a bad tstat.

Also you said you are running a 60/40 mix. Try pure water with Redline Water Wetter additve. This will drop your operating temperature right off the bat.
