Running lean need some help/ported and polished the head 200 1988

Porting the head didn't change the fuel air ratio. Neither did the cam. The mass meter meters the air and adds the fuel that it needs. The O2 sensor checks all that. Something got misassembled or damaged. You don't need bigger injectors. The ones you have will flow for quite a bit more power, and changing them would need a computer change anyways.
