What kind of compression will I get by putting an m20 325 head onto a 320 block with standard pistons? and will it hold boost?

Will the head gasket not seal?

i think the gasket will seal, but it will create a horrible combustion chamber that will over hand the sides of the cylinders onto the block

there was a thread about it in tech fairly recently..
