BTW, for the people who are running stock bottom ends/heads but with metal 
head gaskets (stock on the S6, and maybe on some late S4s too, at least in 
Europe some of them had the metal head gasket from the factory), the 
compression ratio isn't 9.3:1 but 9.0:1 as in the RS2, as the metal head 
gasket is the one and only difference that can affect the compression ratio 
between an RS2 (factory spec at 9.0:1 CR) and an S4 or an S2 (factory: 9.3:1).
