the only thing I don't like about going the fillport way is it won't be as simple to drain. with the petcock I connect 1/4" tubing and put the other end in a bucket. Then just open up the valve and when it's done draining I just close the valve, unhook the hose and refill the loop.
with the fillport, it's just like changing your oil in your car. when you use the allen for the fillport the coolant will want to rush out and may spray when rushing passed the threads.
plus my way is tool less.
haha ya
