    Will this kit fit late model vortec heads. Why do you not sell a turn key kit complete with compatible ECU etc.

    Asked by: Big daddy 27
    No, this will not bolt to the later model Vortec cylinder heads. There are many options for EFI kits so we allow our customer the option to choose the best one that matches their application.
