    L76 intake on a 98 Ws6

    I am planning on doing the l92/l76 combo, and I found a guide for doing it on 99-02 cars. What do I need to do differently with my 98. I have read that the fuel rails will not fit, and that I need a fuel return, but I am not sure if I read that right.

    Those heads won't work on an LS1.
    The valve spacing is different so they need a minimum 4.00" bore (6.0 Block)
