Default ported heads and california smog

hey guys, i have my shortblock planned out and ready, now im just worried about the heads! i got state reffed awhile ago and theres no way around it, and being in california it sucks so i wanna make sure i can pass smog with all my bolt ons turned back to stock, my goal is this

-to have a reliable motor that produces as much power while still being able to pass smog with all the stock bolt ons back on the car, (headers, downpipe, exhaust)

so my question is, will ported heads still pass smog? and also will ported tgv's pass smog as well? i heard they check your ob2 to see if you modified the ecu and deleted any codes, and if i remember correctly ported tgv's give you a cel w/o deleting the codes

You could pull out the butterflies in the TVG's and slide the rod back in. Just make sure of it's position on the gears of each side when you put it back in. This way the sensor will still read the correct position and not throw a code. I do not know the in's and out's of the law in California. Are you allowed to have different maps/ a form of EM? If you're not, then porting the heads and TGV's will probably cause some issues due to increased airflow.

thats what i was thinking, but i also read that ported heads can actually help me pass smog, i forgot the reason why it was late when i was reading, but the guy states since the air has more area to combust that will provide me with cleaner air.

Have you tried to ask in the Cali sub forum? See what people in your state have done. I know that you could get away with the TGV deletes though if you do it as I stated.

First why did you have to go to a referee? You either got pulled over by local or CHP and they ticketed you for something maybe. Yes?

I was just reading on the DMV website that as of Jan. 1st 2005 cars less then 6 model years old are not required a smog test to register. That would include something back to as early as 2001. So if you car is really a 2007 you will not have to worry about a smog test until 2013.

"Vehicles registered in areas subject to the biennial smog certification program are required to submit evidence of a smog certification every other renewal period. Starting January 1, 2005, owners of vehicles six or less model years old will pay an annual smog abatement fee for the first six registration years instead of being required to provide a biennial smog certification. The registration renewal notice mailed to you by the department will indicate if a smog certification is required. If a smog certification is required and you have not had a smog inspection, you may still pay your registration fees to avoid any late fees. However, you will not receive your new registration or year sticker until the smog information has been received by DMV."

That was taken directly from the State of California's DMV website.

"Beginning January 1, 2005, vehicles 6 or less model-years old are exempt from the biennial Smog Check inspection requirement. For vehicles with registration renewals due in the 2006 calendar year, this exemption includes model-years 2001, 2002, 2003, 2004, 2005 and 2006."

Another quote from another website that states the laws of California smog.

I just passed a CA smog inspection. I have ported heads, TGV deletes, big MAF w/CAI, big TMIC, cams, turbo and dyno tune. All I did was put the OE exhaust back on so that it would have CATs and it passed easily.
