    i have a 99 civic ex with the sohc d16y8 vtec replaced by the non vtec d16y7 from a 98 civic dx still using the y8 tranny, harness, and p2p ecu
    it is now throwing engine check light for vtec
    what would i have to do to run this setup, clear ecl and pass smog?

    You would have to get a 99-00 P2E ecu and then move/add some wires for the IACV if your car is a 5-speed or you could swap on the head from a D16y8.

    what would i need to do if i chose to replace the head and put back a y8 again
    im guessing the timing and dizzy right? what else needs to be done?

    You literally just remove the Y7 head and intake manifold and swap over the Y8 head and intake manifold. Dizzys/timing is the same between the two. You will have to swap over the knock sensor from the Y8 as well.
