Well thanks to Elite Pete for supplying a replacement head and the two pulleys that ate each other, the head swap is now under way. Never done one before so need some noob advice...
How clean to the mating surfaces need to be? Are we talking shiny new metal clean, which will take some rubbing with fine wet and dry, or is that too aggressive for the ally head? If so is a crap-scraped-off-and-degreaser-clean level sufficient?
Other than that all going good so far. Pete I managed to drill out that broken exhaust manifold stud at work today.
Oh - I was reading the maintenance guide on the headgasket replacement which is very handy, and it references a guide by Mark DTM on servicing the hydraulic followers. But I can't find that guide?? What can/needs to be done on those? They look pretty unserviceable at first glance other than checking the little hole isn't full of crap which they aren't.
Cheers,
Liam

What caused your pulleys to eat each other?

Get something flat (greater than the width of the head) and wrap some wet and dry round it (200+ grit) and wet it.
Then rub it the full length of the head until its clean and shiney.
Does not take long at all and is very little effort

Thanks guys :y

as with any other engine parts - I'd say they're only really clean enough if you'd be confident licking them.
