im in the process of building my turbo B20 (again) and i decided to use a Cometic head gasket this time opposed to the stock piece. i was going through thier catalog, and i noticed this. the b20 has a stock bore of 84 mm. they list a gasket for the integra b18 with a 84 mm bore, so i figured thats the one, then i see the gasket listed for a crv b20 but shows a 85 mm bore, now i know the crv and the integra use the same head, but im confused as to which gasket to buy. should i get the crv part with an (oversize?) 85 mm bore or what i think is the right gasket the integra b18 with 84mm bore?
