RE-Torquing the head nuts on a 1983 GPz550/KZ550-H2

I have a 1983 GPz550/KZ550-H2. I got a new head gasket but I'm not sure of the torque specs for the head nuts and I'm also not sure of the correct pattern to torque the nuts. I've looked for a service manual online and I've only found a paper version on eBay (I think its for that bike but not super sure) I'll buy it as a last resort but I'm just wondering if anyone here has any information before i buy it.

Have you checked this one?

I have not checked that one but looking at it it’s for an 84 I’m not so sure how different they are and I didn’t see anything talking about torque spec

There is a service manual hosted here.  Check the Filebase.

My apologies, wrong link.

See the table on page xi for torque specs and chapter four (pp. 82-84) for sequence.
