1992 Yamaha 25 hp 2 stroke need head gasket specification

[SanityCheck-27]

I'm replacing the head gasket on my 1992 25 hp Yamaha outboard its a 2 stroke model# 25MSHQ. I know the tighten sequences for the head gasket bolts but don't know the torque values for the head gasket bolts and the cylinder head cover bolts. This is my first head gasket replacement is there anything else I should do. Thank you Robert
