Pablo,..I know these 64HN9 Engines well and found the Head Stud/Nuts Torgue Spec's in an Orginal 64HN9 Service Manual,..160 lbs on Cold Head/Engine and 180 lbs, when the engine is Hot,..Cross tighten from the Center of the Head, crossing over to each side and to the end of the Head Nuts/Bolts. Great Engine when tunned up and with Fresh Injectors, plus Cylinder Kits and have found that their are "N" Series Rebuilt Injectpors available for your two valve head. |
