After some serious soul searching, I went with a closed system and recovery tank from
Brassworks. They hand make them to order and Berg's was out of the range I wanted to spend and I didn't see a closed radiator option. No more spitting hot fluid out the top cap and no more fluid loss out the overflow seemed to be a good idea, plus one can go water-less if I want. I doubt a max of 4 psi will hurt the engine and if the head gasket can't take that, it needed replacing anyway.
