What year, model and cyl number there?
GMC 305 Engine (V8, 305 cid, 5.0L)
Fig. 7: Small-block V8 cylinder head torque sequence (click over image for zoom)
On the 350, tighten the bolts in the illustrated sequence to 100
ft. lbs. When all the bolts have been tightened to this figure, begin
the tightening sequence again, and torque all bolts to 130 ft. lbs.
Install the engine block drain plugs on the 350, the exhaust
manifolds, the fuel return lines, the glow plug wiring, and the ground
strap for the right cylinder head.
Hope helps.
