I was having boil over issues with my roadster, when you have the head off made sure you clean the water passages really well in the block and head long screw drivers, wire, you will be surprised at the amount of rust and stuff that can collect causing hot spots around the cylinders. I don't like to torque while warm or hot, I prefer cold. Look at the block closely while the head is off you may find very small stress cracks, common after adding cold water to a block that just 'steamed' your coolant, regardless of a spinning pump. The biggest drop in overall temp was when I added Napa brand Kool engine, similar to water wetter, it dropped my overall operating temp 30*. I run Sierra brand 50/50 antifreeze.
