I have the sniffer test in my area. What heads and cam are you using? On the engine I have it has dish pistons so i need to keep the combustion chamber smaller for better compression. I am also going to have use the stock TPI until I can afford a mini ram or super ram. I need a head that will pass emmisions and work good on a stock TPI and on a aftermarket one. I was thinking about a comp cam #2040 or 2050.Thanks for any help.

I have a 406 pushing 500 HP and I passed the smog test with flying colors. The heads I have are 195 afr heads. Unless you have an old engine or problems with your fuel injection system you should pass. My CO-% was .36, HC-ppm was 24, and the NO-ppm was 229.check out my engine combo on my web site.link down below.
I have a crane cam it has alot of power.
