Vortecs are a little different that old school small blocks, grab a Haynes or Chiltons, the cross patterns and specs are simply diagramed. Vortec, as any really, start with 25# then 45# and then final torque which I believe is around 70-75# but to be sure verify with the manual. AutoZones, Murry's, Adavance auto all carry the books, Cheap insurance.

Because torque specs vary from engine to engine, it is best to run your vin # at a auto parts store and they can give you the torque specs for your heads. As for the sequence, you always start in the center of the head, top to bottom, and then move outward, taking the bolts down in 3 stages. Do one stage, come back and do a second stage and then a final stage. Run you threads down dry. No goup.

Intake manifold torque specs and sequence for small block,Chevy 350 engine


Depends on specific engine ( truck/car, vortec/ non vortec, year, etc). Best place is to call any of the chain stores. They can print all those specs out based on the vin and year of the vehicle.

I need to know the torque specs for the head gasket for a 96 3.8 chevy camaro


Tighten the cylinder head bolts to 50 N·m (37 lb ft) in sequence.

Use a torque angle meter to rotate each cylinder head bolt 120 degrees in sequence.

Use a torque angle meter to rotate the four center cylinder head bolts an additional 30 degrees in sequence...

I hope this helps.
