I Don't agree with the statement that rare parts not available and the line held up. There are tons of jan and feb 842s[nov dec 68 as well] made, and 3 or so dates in each month, hard to believe with those cast dates and only so few cars made theyd run out of heads...… The heads on the car would have to be march or close dated if they weren't available when the car was built. As far as the build date on pad,who knows......if you combine that with the fact I have 6 sets of feb heads with zero plugs,that tells me probably the plugged head is not feb or march, but earlier
