With respect to thermostats, I recently contacted Roush on what brand/temp they recommend. They were extremely nice and sent me a 160 deg F with a hole drilled, specifying that the hole should be in the 12 o'clock position for install. Maybe this solves Roush's perspective on the question of no hole vs hole... The thermostat looks just like the a premium one you'd get from NAPA for a 351W engine. It does not look like the one I received with the engine.
