Anyone in Southern California running a XE274H or XE278H cam in their 4.6 and getting it by smog.

I already have to put the stock tune back in the ECU and the stock mid-pipe back on for inspection. It sails right through. My new engine will be using the Twisted wedge heads and I would like to use one of those two cams.
