It's 86mm. Contract Greg V and let him know the bore size. He will get you what you need

Gasket size is usually 1 mm larger than bore.

I called Cosworth and they list 87mm as Std bore +1mm this is after talking to their rep he stated they list actual bore of gasket not bore of engine. so 87mm actual gasket bore for 86mm engine bore. IDK about Cometic size listing but if its the actual gasket bore then ok if its engine bore than no bueno
