Default XR6 Head Enquiries

Hey Guys & Girls

Does anybody out there know the exact differences between the standard and XR6 head, I've heard the intake valve heads are 2mm wider and the cam has a slightly more aggressive grind on it, would it be worth putting one of these heads on my standard 4.0? if so what are the advantages?

Cheers, Daniel

I wouldn't think the valves are any bigger but they do have a slight more aggressive cam over a standard 4.0 cam. Your better off putting a wade or crow cam in.

Your head would flow a bit better and you get a slightly larger cam. You might notice a small gain.
