Re: radiator selection

The steam line in the radiator hooks to the steam lines that are bolted to the front of the heads. Some people tap the water pump and hook it to that, some people cap them off and say they don't have a problem, but GM put them there for a reason, to get all the air out of the system to keep from creating hot spots in the head is what I'm told.
