    I'm looking to replace my 1991 vet L98 motor ,, but I think the zz4cam and 58cc heads will restrict the potential of the zz4 motor..... Would you sell the the motor with a zz9cam and with out the heads ??

    Asked by: Dill
    This is a short block with no cam or heads so you can add the components you want to complete the assembly.
