  • S14 Head Question ...

    Wondering if there is any difference in the head manufacturing/castings by the casting year seen on the front end of the heads.

    I've got three heads on hand and was wondered if there was any difference between the 87,88 or 89 heads?

    Thanks for your help with this.

    If any difference then not relevant ones.
    The machining made the difference between the final cylinder heads.
    Can't say if the s14b25 head used the same casting as the s14 20 and b23
