    Hey there,
    I was wondering what it means when someone says that the head of an engine is "shaved"?? I have never heard this terminology before. What does it envolve? And what sort of power can you expect from this job on a JDM D16Z? or just in general.
    Thank you much.

    "shaving" or "milling" the head is when the gasket surface of the bottom of the head has material removed from it. Sometimes its needed to make the surface "true" or "level" again, and others do this to raise the compression ratio.

    Basically it's to ensure the mating surface on the HEAD to BLOCK are FLAT or LEVEL. To ensure the mating surfaces are even. Better seal so to speak/.
