Me too

Back to the beginning I think. I can't see it being anything to do with the stat, unless the b bolt and engine mount plate can foul anything in that area? Don't really want to disturb it again as the coolant seems ok, etc.
I can't feel or see anything trapped in the cam covers, and although I don't really want to remove them again (I did remove and inspect at the start of this) I may have to. I have had the plenum and inlet off and on several times and don't believe I could be doing something wrong in that respect on every occasion?
There's nothing to the sandwich plate either, providing all seals are present.
Suppose I may have to inspect the timing again, ensuring tdc, though I don't believe the problem lies there. It would just be something else to rule out ...... again!
Tried a garage with no joy. I guess Vx might just be the same, only more expensive

Compression test too I think, just to check.
Although I don't understand engines, etc I did think the replacement coil packs were the answer
