po172 and po175 codes
Has the car been tuned with the bolt-ons? That is too rich on bank 1 and bank 2. Could be bad maf, esentially it is more fuel than air and the O2 sensor is reading more fuel.

Found this site to help you try and troubleshoot, is the MAF plugged in?

I was getting o2 codes when my fuel pump was bad. I could erase the codes with my scanner and drive around for weeks and several miles without it coming back on if I drove normal. If I went WOT, the codes would turn on and activate the check engine light again. I replaced o2's, a MAF and spark plugs before finding out it was my fuel pump. My car did have a little bit of a hesitation at times, particularly whenever I'd give 3/4 throttle or more, and the car didnt run as "beastly" as I felt it should on the butt dyno. Not sure if you're experiencing similar issues.

I think I figured it out, it looks like i forgot to reconnect the line from the purge solenoid(sits on the passenger side head front) and the other end that connects behind the throttle body after installing the heads. I'll have to put some miles on it now and see if that solves it, thanks for your help. The lines were set in position but i never pushed them to there locking position. I guess it pays to check and double check.
