I've only worked with OBD1/2 d-series, and was wondering if a 3-layer z6/y8 head gasket will fit on a 1987 Civic D15 carb motor, and also do these motors have studs instead of head bolts, so no need of replacing them? What would the torque specs be?

This is my friends car that he needs to get running soon, and help would be appreciated.

Thanks
