    The X usually stands for the ex.flange angle

    Does that make a horse power or performance difference. Do they have different angles for dragster vs funny car ?

    I don't believe BAE rates H.P. or performance for there heads usually newer are supposed to be better -

    If I remember correctly the 8X has larger valves and sometime right around the 8 and 8X heads they changed the exhaust flange angles.

    Hope that helps,

    Talked to BAE. The valves are the same diameter it is the angle of the exhaust port and the short turn length of the exhaust runner
