parts i should renew other then gaskets

[johnny_boi85]

im about to change my head gaskets on my vt v6 ecotec motor because long story short i pulled the motor apart and had to quicky put it back together with the old gaskets still in it just wondering what other parts besides all the gaskets should i replace while my motor is apart. the car has done 220.000 and im doing a full service while i do the head gaskets aswel.

If the engine is already apart, I would replace all the bearings too. Maybe time for some new piston rings too.

i just got a gasket kit so im going to do everything that comes with that if i do the rings and bearing i may aswell do a rebuild on the whole motor dont think i wanna go that far im getting a new 02sensor atm my engine light keeps coming on i tryed to self diagnose by bridging that part under the steering wheel but i cant figure out what number it is saying
