    Hey i have an ls with bent valves and i was wondering if a b20(p8r) head will fit on it, Considering that the port size is larger on the p8r head.

    I know a b18c head will fit on a b-20 block

    And a B18c head will fit on a b18a/b block

    So logic would indicate that a B20 head would fit on a B18a/b block.

    Anyone with a confirmation?

    If you use a b18 block with a b20 head, wouldn't this lower compression?
    I know that if you use b16 head on a b18 you increase compression which gives more power, if you go the other way my guess is that you will loose power.
