Sounds like a great spec. you have chosen. I too would be very interested to hear results.
The pictures of cam belt area showing what looks like grease is probably leaking oil mixing with belt debris. I note you have the early sealed belt cover with gasket, so the debris and oil would have been trapped inside.
FWIW I am just having new cam seals fitted under warranty to my barely three month old car to correct slight weep from two of the three camshafts. Apparently MMC sent the dealer a complete new belt kit so not sure if the whole will be fitted. Seems a bit extreme given that probably only two seals were needed and that I already have latest spec engine.
