OK folks, I am working on a 71 AMX 360. I have had several AMC V-8's and have never had this issue. There is a colant leak around the exhaust port on my number one cyliner. There are no freeze plugs in the area. The head was ported and polished if that matters. I don't see any obvious cracks. Are the header bolts wet in that area? I installed them without sealant as I have always done in the past.
