hello, here is the torque procedure for the cylinder head from the service manual.
Cylinder head bolt torque sequence
The 1991-98 cylinder head gaskets used on the 4.0L are a composition gasket. The gasket is to be installed DRY. DO NOT use sealing compound.
Install the cylinder head and bolts. The threads of bolt No. 11 must be coated with Loctite® 592 sealant before installation. Tighten the bolts in 3 steps, using the correct sequence:
Tighten all bolts to 22 ft. lbs. (30 Nm).
Tighten all bolts to 45 ft. lbs. (61 Nm).
Retighten all bolts to 45 ft. lbs. (61 Nm).
Tighten bolts 1 through 10 in sequence to 110 ft. lbs. (150 Nm).
Tighten bolt 11 to 100 ft. lbs. (136 Nm)
Tighten bolts 12 through 14 to 110 ft. lbs. (150 Nm)
Cylinder head bolts should be reused only once. Replace the head bolts which were previously used or are marked with paint. If head bolts are to be reused, mark each head bolt with paint for future reference. Head bolts should be installed using sealer.
