Three different sealents.
Never found a V6 head that needs skimming yet!
I reacon about 150 quid for the bits and a days work.
Thanks M_DTM 
Just get the HG, or a gasket set?
Also, chances of the threads on cooler stripping during removal? Is it worth getting a cooler kit, and reselling on if not required?
The 3 sealants - green, grey, and black?
Aiming to do later this week, with a bit of help from someone - hopefully Fri/Sat - I suspect it will take us more than a day 
Just get the gaskets, the rest of the stuff in the kits is crap.
You need three different types of sealent.
1) Black for the cam covers
2) Green for the front bearing caps
3) Grey for the oil cooler plate.
With the heads off you can get the oil cooler out still attached to the plate so no risk there.
I have a set of 3.0 heads ready to fit sat on the shelf I can do you as an exchange pair (you would need to buy 24 stem seals so I can re-furb your old heads).
Is the crank oil seal ok on yours?
