Compression ratio?
As far as I know the EVO's (IV-VIII) has an 8,8:1 compression ratio. If I install a HKS 1,2mm head gasket how much would it lower the compression if everything else is stock?

According to Boost solutions, the 1.0mm gasket makes 8.6:1, and 1.2mm gasket makes 8.5:1.
"HKS Metal Headgaskets
HKS offers 1mm and 1.2mm for the Evo8
- both are 86mm bore, but the compression is 8.6 and 8.5, respectively"
