On the 1.6s with the standard head gasket I like to clean the surface of all oils. With the metal head gasket it doesn't seem right to leave two metal surfaces without any corrosion inhibitor. Super clean it? Or spray/wipe a light oil on it?
if your RA finish on your head and block are not fine/smooth enough it may take aviation gasket sealer to get it to seal....they were not originally set up for that fine of a RA so there is a chance it wont seal...like mine did not...I took mine back off aviation gasket sealed both sides and it's been holding fine.my .02

No taking chances for me.

I was also wondering if ARP cosworth headstuds are better than stock 12mm headbolts when using these metal headgaskets so I'm glad you brought up torquing the headstuds/bolts. I was reading over on TDI club about torqueing ARP headstuds with a metal gasket and remember your encounter with them. Aviation sealer if the surface isn't perfect? The block was surfaced and looks great. but I don't like to surface a head if it doesn't need it; having an overhead cam and all. and it didn't look bad. What does RA mean?
Frank says 6 RA on the TDI(metal gasket with teflon looking coating), and the head i just got back from him is baby bottom smoothhttp://forums.tdiclub.com/showthread.php?t=175661
