I tried to paintakingly research this same question when I did a total engine resto on a '70 SS I had last winter (it can still be seen at
www.yearone.com/Customer's Cars I believe). I painted the round motor part cast-iron and used Silver Cadmium on the upper square portion. I'll email you an image which I believe will show this combo pretty clearly.
P.S. I didn't want the URL reference to show up as a link but I can't get rid of it ...
