Hey there, I noticed that you are needing a head torque for your Kohler engine. While you are waiting for an expert to answer your question, A suggestion that I have is to visit SearsPartsDirect.com I have attached the link below. Hope this Helps!
I have included a set of illustrated instructions (See below). These should step you through the process of installing the head of your Kohler engine. I am not sure if you have bought new head bolts but it is advised to install new head bolts when replacing the head gasket. Per the repair manual, the coating on the bolts will come off and will not tighten correctly. I hope this is helpful.
