Hey Harry! Sorry to hear about your arm, I guess, it's full recovery ?
And that head looks almost spotless, is there any oil even there lol ? What's the mileage it has to be very low
FWIW what may be worth doing is checking that the CAS sensor lobe at the back on the intake cam isn properly lined up. I've heard they can move on the VVT engines, from Skuzzle. It's only a friction fit but after a some expansion/contraction it appears to loosen up.
If I had the vvt engine I'd get it drilled and (tapped and screwed)/pinned into the cam.
