I designed a surge tank last week and had my local machine shop fab it up for me. It consists of a billet upper neck with a 1/8″ NPT port for a -4 overflow line. On the upper front a -8 weld-on XRP double o-ring port that leads to the top side of the radiator. A weld-on -4 AN nipple at the top side for the steam ports. Then at the bottom left two -8 weld-on XRP double o-ring ports for a pass-thru from the heater core to the front inlet port on the water pump:

All of the lines mocked up:
