Hey Dan you can increase the depth some also. You probably won't need to with a heli-coil. If you do break through the threads can easily be sealed with a bit of silicon, thread sealer or PST on the threads. The tap will say STI on it which stands for standard thread insert then you'll have the thread size (3/8"?) after that. If you feel inside the coolant hole I believe there are bosses there for the holes you'll be able to get an idea of the depth. Pretty straight forward job worth doing to both while you're set up.
