Someone at GM put that paint on there.. I 'think' these were the first forms, of the double hump heads, that we all came to love on 283s and 327s...not sure, but I think so. The first 461x heads. You did not see another aluminum head on a chevy until 67, and it was a big block. Note on the last picture, how GM tech milled out the valve seats on one cylinder so you could not use again. Easily repaired today.
