tons of O2 codes these all came up after i put on 243 heads and lt's
P1153
P0133
P0135
PO140
P0151
PO155
P0160
is it possible i jus have bad O2 sensors or is there something else going on?
...the downstream O2s show no activity because i still have to get it tuned out (no cats)

Sounds like you removed your rear O2's, so you can disregard any codes referencing 'Sensor 2'. You can see a list and description of all the codes here. It is not uncommon to experience P1133/P1153 particularly after a header install. Search is your friend. 
Lots of suggestions. Could be your sensors, you could try some Bosch 13111's or some vette rear O2 sensors. There are some tuning settings that can also be made. Some of the other codes also show up after a header install. You should read this thread.

this really sucks... i really don't wanna shell out $$$ for new o2's. should i just spend time looking for leaks?? leaks AFTER the o2's are insignificant correct?
