Trying to figure out how to read date codes on a pair of hemi heads.
Both has the following numbers cast into them
2780559
X
CWC
One head has M17 the other has M57. I am assuming the head dates are the M17 and M57 numbers. If so what do these mean?
thanks much
matt

M17 - M = November, 1 = 1, 7 = 1967; (11/1/67)
M57 - M = November, 5 = 5, 7 = 1967; (11/5/67)
