Hello everyone,

my name is Max, i'm french
I bought an engine 2300 complete galaxy for my rs2000, with a cylinder head gasket of 2l3, to assemble with the head of engine 2000
But my mechanic tells me that the compression ratio is too high
I would like to know if there is a strengthened cylinder head gasket, as well as a way to lower the compression ratio, because there I don't know what to do anymore
Thank you in advance
