From autozone.com:
To install:

  1. Thoroughly clean the gasket mating surfaces. Remove all traces of old gasket material. Remove all carbon deposits from the combustion chambers. Lay a straightedge across the head and check for flatness. Total deviation should not exceed 0.001 in. (0.025mm).

The cylinder head gasket used on the 2.5L engine is a composition gasket. The gasket is to be installed dry. Do not use gasket sealing compound on the gasket.
  1. Fabricate 2 cylinder head alignment dowels from 2 used cylinder head bolts. Cut the head of the longest bolt off below the hex head. Then cut a slot in the top of the dowel to allow easier removal with a screwdriver.
  2. Install one dowel in bolt hole No. 10 and the other dowel in bolt hole No. 8.
  3. Place the cylinder head gasket over the dowels with the numbers facing up.
  4. Place the cylinder head over the dowels.
  5. Coat the threads of bolt No. 7 only, with Loctite PST sealant or equivalent.
  6. Install all head bolts except Nos. 8 and 10.
  7. Tighten the bolts in the sequence shown in the illustration to the following:
    1. Tighten bolts 1 through 10 in sequence to 22 ft. lbs. (30 Nm).
    2. Tighten bolts 1 through 10 in sequence to 45 ft. lbs. (61 Nm).
    3. Recheck bolts 1 through 10 in sequence to verify that they are 45 ft. lbs. (61 Nm).
    4. Tighten bolts 1 through 6 in sequence to 110 ft. lbs. (149 Nm).
    5. Tighten bolt 7 to 100 ft. lbs. (136 Nm).
    6. Tighten bolts 8 through 10 to 110 ft. lbs. (149 Nm).


During the final tightening sequence, bolt No. 7 will be tightened to a lower torque than the rest of the bolts. Do not overtighten bolt No. 7.
  1. Connect the temperature sending unit wire.
  2. Install the spark plugs.
  3. Install the compressor.
  4. Install the compressor/alternator bracket mounting bolt.
  5. Adjust the alternator drive belt.
  6. Install the air conditioning compressor drive belt.
  7. Install the intake and exhaust manifolds.
  8. Install the power steering pump bracket.
  9. Install the pushrods. Keep them in order!
  10. Install the rocker arms. Keep them in order!
  11. Thoroughly clean the mating surfaces of the head and rocker cover and install as outlined earlier in this section.
  12. Install the air cleaner.
  13. Connect the hoses at the thermostat housing.
  14. Connect the battery ground.
  15. Fill the cooling system.

Cylinderhead torque settings

I'm not sure what engine you have in your 95 grand am SO I will give you both the 4cyl and 6cyl Specs. Also you didn't ask for the torque sequence. I will include that as well for both. 2.3 DOHC Quad 4cyl: Torque sequence---> front ' 7 3 1 5 9 ' of engine ' 8 6 2 4 10 ' Step 1: torque bolts 1 thru 6 (26 Ft/Lbs & 90 degree turn) Step 2: torque bolts 7 & 8 (15 Ft/Lbs & 90 degree turn) Step 3: torque bolts 9 & 10 (22 Ft/Lbs & 90 degree turn) Recheck final torque in sequence *** CAUTION *** This engine uses "Torque To Yield" (TTY) head bolts that means they permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed in order to obtain proper torque. 3.1 liter V6 Torque sequence--> ' 6 2 3 7 ' ' 5 1 4 8 ' Step 1: torque bolts in sequence to 33 Ft/Lbs Step 2: turn an additional 90 degrees Recheck final torque in sequence *** CAUTION *** This particular engine uses "Torque To Yield" head bolts(TTY) (that means the bolts permanently stretch during the initial installation.) You MUST use NEW head bolts when replacing or reinstalling the cylinder head in order to obtain the proper torque.
