I just put long tube headers on my 99 Z28 with new o2 sensors and they are switching very slowly, the AFR is not steady on my wideband because of this. What do I need to adjust in the tune to fix this? They are Texas Speed headers & Denso O2 sensors. The car doesnt have a cam or any major modifications.

Try to shorten the integral delay and change the switch points to 450/450. see if that helps.
