what kind of comp ratio?

well as some of you know when going to put my turbo kit on i ended up having a blown headgasket. now the apt complex wont let me finish putting my car together so im stuck. ANYWAYS

so i bought a 3mm head gasket for INLINE PRO and some of their cam gears. what kind of comp ratio am i looking at with b18c1 block/b17head with the new headgasket. stock block

thanks
