I will include you all fastener specs. My question to you before you waste a gasket, did thread inserts get installed in the block. Typically when head gaskets fail on these it is a result of lost bolt torque due to pulled threads. There is a procedure to repair these using what is called a timesert, and is recommended that they be put in all holes at the same time. If you only have one head off, you should do all holes on that side. Here are the specs:
