[s-cars] RS2 compression ratio

[Dave Forgie]

As a result of my never ending search for S-car magazines (originally
for S4 and S6 articles), I have also branched out and aquired many
magazines with S2 and RS2 articles  One thing that shows up consistently
in the RS2 articles are statements that the compression ratio of the RS2
engine is 9.0 to 1 (not 9.3 to 1 like the AAN).  I presume that if this
was true, it would be the result of Porsche installing (or spec'ing a
thicker head gasket).  Could someone with a working ETKA confirm or deny
the thought that the RS2 head gasket has a different part number that
the AAN head gasket?

TIA
