.
the reason to do it on a race car or even a stock car is so you can separate the coolant section of the intake manifold from the main body of the intake manifold. you can separate the two with a cut off wheel. once they are separated this allows you to change intakes at the track very easily without breaking into the coolant passage. another reason to do it is that these o-rings leak, if yours doesn't leak then you got lucky but I bet if you look right behind your water pump on the top of your valley pan there will be a little puddle of coolant.
