#349339 haha thanks teal little late though, it was a brand new sensor when I put the motor in, ( less than 2500 miles now) couldn't get the old one out of the other manifold, and since I made my own custom engine harness, I didn't have to do any modification, just pull the loom off about 6 inches, and re wrap what I undid, fit with some extra slack to spare haha, I did however notice that my o2 sensor was blacker than night (obviously since it smelt like a carbed 350 at start up) and gave it a gentle wipe with a towel...im just worried that it might have already damaged the sensor but so far no check engine lights and it seems to have leaned out enough, not smelling too rich anymore, but I did reset my ecu so after a few hundred miles the verdict should be in. I think all in all it took me about 25 min to swap bungs and unwrap and rewrap it all...so even if it causes more harm than good I know the switch back will be fairly simple...although I will say using anti seize on the 02 sensor was a smart call haha. and bung plug....sometimes I wonder why things get named the way they do haha..

#349795 400 miles later running good no rich smell, mpgs are up and it feels smoother to drive, definitely a wiser choice than buying a new header :thumb:
