The repair manual specifies "tight". None of the bolts are high strength steel so torque on all of them will be less than you expect. I would suggest 60 ft-lbs. max on the head bolts. Some will likely stretch or are already stretched so inspect them closely and take it easy. Other bolts will be in the 10-35 ft-lbs range depending on the size. Remember that the compression ratio is ~5:1 so not as much pressure is required to hold the head and keep it leak free.
