    How about a code of C80E D 302 heads I was told they used them in 1968 on the 302 they stamped on top with 302 4V would like to know what they are off thanks please send me a email at dlaymance@live.com thanks for any help

    • That stamping was designated a 68 289 usage. Now I would not be surprised if one of 2 things is going on here. 1) They were a swap out at some time in the engines life. Not a real issue. 2) Other than a replacement by the owner at the time for a another set of heads or even the possibility of a substitution at the factory or dealer in it’s early days. Such as a head job with an exchange. No biggie. This is actually an acceptable combo.
      Thanx for your interest! BzeroB

    I have one 289 head marked C8AE. What do I realy have. The other head is a C6OE which is a 54cc head. Are they a good match or is there a major difference in chamber sizes
