You are referring to the cylinder head bolt-torque sequence. Here is the instructions, then I'll clarify.
The cylinder head is made of aluminum. Over-torque of bolts can result in warping or cracking of the head. Also, some of the head bolts go into the water jacket. Those bolts requires a teflon sealer or water will come up through the threads and result in coolant leaks. Use a thin wood dowel to probe the cylinder head bolt holes to see if they bottom out or go into the water jacket.
When you tighten the bolts, do it in the sequence directed, up to the toque specified for each length bolt. Once that has been done, you will make one more circuit of the bolts, tightening each one by 90 degrees. The easy way to do this is to place your torque wrench on a bolt with the handle pointed at 6 o'clock. Tighten the bolt another 90 degrees, or when the handle reaches 9 o'clock. 90 degrees is 1/4 revolution of the bolt. (You can start the wrench anywhere that is convenient to make the 90 degree advance without interruption.)
Hope that helps!
SOURCE: chevy cavalier need torque specs for 4cylinder heads
What torque specs and what engine/trans combo?
SOURCE: 96 cavalier torque specs
70 Foot pounds (Final torque) if it is a 2.2
Torque in sequence
Step 1: Torque to 15 Ft/Lbs
Step 2: Turn an additional 90 degrees if it is a 2.4 sfi dohc
SOURCE: need cylinder head torque spec 2001 cavalier 2.4
Cylinder head torque
Step 1
Bolts 1-8 40 lb ft.
Bolts 9-10 30 lb ft
Step 2
Tighten all bolts an additional 90 degrees.
Note this info cam from Mitchel
These bolts are torque to yield meaning they must be replaced after torquing once. In other words the are single use bolts. DO NOT reuse them!
Hope this helps
SOURCE: TORQUE SPECS /HEAD GASKET/2001 CAVALIER...
for the 2.2L OHV:
(pully 8 4 1 5 9 <-- long bolts @ 63Nm (46ft/lb)
side ) 7 3 2 6 10 <-- short bolts / 10 is the stud @ 58Nm (43ft/lb)
for the 2.4l
dohc are as follows:
(pully 9 3 1 5 7
side) 10 6 2
4 8
bolts 1-8 torqued to 65Nm (40ft/lb)
bolts 9-10 torqued to
40Nm (30ft/lb)
then (either engine) give each an additional 90° (¼)
turn
it's best to do
the tightening in stages, you don't want to go completely tight on the
first pass or there will problems and you'll get to do it all over again

Tighten bolts in sequence, tighten the long bolts to 46 ft. lbs.
(63 Nm) plue 90 degrees. Tighten the short bolts to 43 ft. lbs. (58 Nm)
plue 90 degrees.
Hope helps.
