I could swear the XE268 was one of the choices from the beginning...lol. The 268 will have a slight chop with manifolds. It's smooth with headers and static around 9.8:1. Better heads can use smaller cams well, and fora car with full exhaust you want more lift and duration on the exh side because the scavenging isnt as good with them. That's the real basic stuff anyway. Hopefully some of you research told you that.

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
