    I'm thinking I haven't done this yet because of the exhaust ports being different? Are they different (round vs square)? Anyone do a Vortec head swap on their EFI 350? Whats needed in the swap? Thanks, Jeremiah /forums/images/graemlins/k5.gif

    To do this you will have to get the TBI Vortec intake from GM and the EGR setup. Scoggin Dickey has everything you need and can talk you through the process.

    OUCH! thats high dollar stuff. I'll just port and polish my heads and be happy. I got the holley throttle body so I need to trim out the intake to accept it and I'm thinking about doing the cam too. Thanks for the link. Jeremiah
