This is the way i have been doing it since i was taught back manymany moons ago , First ya cgase all the head bolt holes in the block with a bottoming tap then using either or laquar thinner or carb spray cleaner to gut the oil and grease then blow dry then clean and chase all the head bolts and wash them and dry them , then lube the thread litely with white grease copper coat the head gskt both sides and using dowel bolts to guide the head down on and also hold the head gskt. install all the bolts and starting in the center and going by the book tighten them down in three setps starting at around 35-40 ft.lbs. next between 65-85 then to the final torque then set valves put the oil and WATER to her then run her to working temp and i like to let them run in for over a half hour to and hour under somewhat of a load so everything gets warmed up but if ya don't have a dyno then cover the raditor and watch the temp. gauge and let her get up to mid range in the work zone and stay there for a spell so everything is warmed up . Then gp back around all the bolt in order pullen them down to the limit and if your usen a clicker torque wrench then i like to hear her click three times on each bolt . then reset the valves and go over them a couple times and your good to go.
