    Yes 243 heads for the 3.9 bore. The L92s and LS7 heads for bigger bores flow huge numbers.

    If you can't use 243's and you cannot port them the 241's make maybe 3-5 more than 806's or 853's. This is due to a smoother casting finish due to a different casting method. All three have the exact same port design so once ported they all have the same potential.

    I would spend money on a GOOD valve job as that will give you more than the difference between these heads....

    Of the ones you listed, the 241s are the best.
