CAN I USE MY GT40p HEADS on my street mustang and be "smog friendly"?
HI! I just got a FOX-Bodied Mustang! All of my other cars were carb. I have GT40-p heads. I have full length tube-headers with O2 sensor bungs. CAN I BE LEGAL using these heads living in CA? I have read that the GT 40p heads were made in such as way as to be able to smog the 5.0 with the newer (at the time) laws - therefore the heads were revised to be cleaner, more efficent, deleting the need for the smog pump. Is this true?
If I JB weld the air tubes to the heads to pass visual check will I pass the sniffer?
