I have about $1600.00 to spend on new heads for my A4 block 331. It will have a TFS R intake, 72# injectors, about 20 pounds of boost, and a custom blower cam. I am also considering putting long tubes on it. I live in southern California and the smog laws are really tough. I have a dedicated drag car, so I don't want this car to be too radiacal. This car passed the smog inspection with no problem. It made 472 to the wheels with the cats on it. I would like to see about 650 to the wheels without the nitrous(80 shot). I am leaning towards AFR 185's or possibly 205's. I have 205's on my drag car, but like I said this is a street car. It doesn't even have a cage in it. I am going to install one while the engine is out. The car weighs 2800 pounds and has got a Lentech AOD and a built 8.8. Any suggestions would be appreciated.
Thanks
Doug
