ignorant question about o2's

im doing an lt1 swap and im not at all concerned with emissions. i know i can delete rear o2's, but dont i have to keep the fronts? i think they are what determines the air/fuel ratio so im pretty sure i need them but just want to see if there are other options. thakns

I think you mean open loop. Closed loop uses the O2's.
