Guys I have the sep 2000 AU XR8 185kw motor
wanting to know if this already has gtp40 heads on it Can I fit gtp40 values & springs to it, if its not the Gtp40 head and how much would they cost roughly lastly rocker rollers - about how much do a set of these usually go for |

As far as I am aware the AU 185kw XR8 did have GT40s on it. EL XR8s with 185kw still had E7 heads. Although the GT40s are better flowing than the E7s they still had the same power but they did have more torque.
Hope that helped. Roller rockers I'm not sure how much but I would go for something like the Yella Terra 1.72 ratio. I would get an engine builder to check but I dont think the valves come into contact with the piston with the 1.72s. |

Yeah all AU V8's had GT40P's. Some Yella Terra 1.72 ratio rockers (ST2027) should be around $460.

The 220/250's also had GT40P's although they were modified. EL2 XR8's still had the E7's, not GT40's. |
