    Worn valve seals or valve guides. The rings would be bad, if you saw blue smoke almost all the time.

    Rings, no. Valve seals, possibly. It will require some specialized tools. Too bad the valve seals weren't done while the head was off.

    You should be able to drive it--it will just smoke. Plugs will really get fouled and it will pollute. To pass emissions testing, it will obviously need to be fixed.
