It's not that bad a job, but it is an all-alloy engine, you have to be religious about using the correct torque procedures and settings, and use a composite gasket on the rebuild after a skim.
Get the valves done while the head is being skimmed, don't forget to renew the head bolts and valve stem seals.
Get a copy of RAVE for all the bits and pieces of info, like putting the rocker shaft and pedestals etc back the right way round so you don't block the oil feed....
