Autozone.com has the repair manual for this age of Taurus / Sable on-line. (See link below)
The following applies to both types of 3.0l engines, including the DOHC.
From the section on replacing cylinder heads:
Position the cylinder head on the block. Install new cylinder head bolts and tighten, in the sequence illustrated as follows: # First pass: tighten the cylinder head bolts in the sequence illustrated to 52-66 ft. lbs. (70-90 Nm), then back off the bolts 360 degrees. # Second pass: tighten the cylinder head bolts in the sequence illustrated to 45-55 ft. lbs. (34-40 Nm). # Final pass: tighten the cylinder head bolts in the sequence illustrated to 63-73 ft. lbs. (85-99 Nm). Here's a text version of the torquing sequence - the repair guide has diagrams:
BOLTS - # in sequence
6 4 2 8
5 3 1 7
The cylinder head bolt torque specification is 90 pounds. The cylinder head bolts should be torqued in 30 pound intervals.
30 NM 50 NM then 90°
30 NM 50 NM then 90°
The head bolt torque specifications, for your Honda Accord 2.2 liter engine, is 120 pounds per square inch. The head bolts should be torqued in 30 pound intervals.
The cylinder had bolt torque specification is 90 pounds. The cylinder head bolts should be torqued in 30 pound intervals.
Tighten the head bolts in 2-3 steps to a final 30 NM
The Kawasaki 110 cylinder head bolt torque specification is 120 pounds. The cylinder head bolts should be torqued in 30 pound intervals.
CAUTIONTo prevent cylinder head damage, GM recommends the usage of a Remove Cylinder Head Bolt Sequence with a cold engine. For installation, always use NEW cylinder head bolts.

Head Bolts: 1. 15ft lbs 2. 30ft lbs 3. 37ft lbs 4. loosen 1 bolt 2-3 turns then do final torque before going to next bolt. Final torque: Long bolt 30-37lbs +180 degree's (1/2 turm tighter) Short bolt 15-22lbs +180 degree's (1/2 turm tighter) Yes, it seems odd to loosen a bolt once it's tight but it is what ford recommends. Tighten all bolts to 1st torque setting then 2nd and then 3rd. Once all bolts are tightened to 37 ft lbs you must then loosen 1 bolt 2 to 3 turns and re-torque (29-37 long bolt or 15-22 short bolt). Once torque setting is reached you then tighten the bolt 1/2 turn more. Do this for each bolt. Loosening and re-torque only 1 bolt at a time. I have seen the Ford service bulletin that confirm these settings.
