Revised the thermostat housing. Since I live in a hot climate warming up the car won't be as much of an issue. The 3/8 will circulate water into the block bypassing the radiator. Since the bypass is not going through the radiator it should warm up quicker. Once the thermostat is open the water takes the path of less resistance which is the -16s. It's the same concept as most have done with drilling holes into the thermostat when they delete the crossover. The other 2 ports are for adding temp sensors if I want to monitor temps from that spot in he cooling system.
