We are looking at possibly having some custom 3800 heads made for both the SC and NA engines, for both S2 and S3 engines. They will be aluminum heads with splayed(canted or off sex axis) valve centerlines. meaning the head will look like a porcupine, or like a BBC or a 3400 alum head if you get the picture. I am looking right now for people that are interested in these performance heads. They will inherently flow more than most extreme ported heads, and will be designed by a very top notch high quality company. If you want to know more, let me know. IF i posted this in the wrong place, also please let me know.
