not sure on your spec,check with a manual,spring sizes,loads and valves.valve rotors turn the valves on the exhaust valve-for better or worse on the seat

If your engine is truely an AU3 XR8 220 then they do not have standard GT40P valve tip lengths. Earlier AU XR8's and all non-XR8 V8's did have those valve tip lengths.

The AU3 XR8 220's had a very bad combination of springs and retainers. The springs had 4-6mm of slop in the factory retainers. I ended up choosing a Crane retainer and Comp Cams spring.
