    What head CC might these be

     



    I have an engine I took out of a 98 Z71. 350 FI. The heads have a three tooth saw tooth on the front and back. Looking under the valve cover all I can find is L207 and GM 0. There is a guy that is interested but wanted to know what CC they are. Does anyone know or is there more info I need to provide?

    A number would be good - usually in the middle of the head, between the center valves..

    Find the casting numbers and someone can identify em for you.
    Casting numbers will be under the valve cover area, 7 to 8 digits,first 2 numbers will probally be 10.
