Need Manifold Bolt Pattern

I've been searching lately for a spec sheet that has the diagram for the exhaust port and bolt pattern for the exhaust manifold on a B18B ( 98 Integra LS ) engine. I'm just trying to avoid buying the gasket and doing the math to locate the exact position of each hole. I'm not sure if they include such a spec sheet with any aftermarket headers, but if anyone has access to such a thing or know's who to ask, please let me know.
