Default Re: 1969 Z/28 Original Radiator w/ 'UH' Tag

Not pertinent to the rad question, but M-coded heads denotes a foundry evaluation piece, rather than a casting date code; similar to the M-code block castings described in the CRG drivetrain decode section. I have a pair of 'M' 186 heads on my Camaro.
