    Hi:

    The most accurate way to determine what heads you have is to measure the intake port size and post a picture of the combustion chamber side of the heads.

    Casting numbers are notoriously misleading,...

    If you'd taken all of 2 seconds to search, you'd have found your answers in this thread:

    If they have MFI ports, they are almost assuredly the 'E' heads, as they have the same port and valve specs as the 'T' heads.
