Head bolts should be tightened most of the way in a star-shaped pattern. Bolts should then be tightened completely following the same pattern as the first tightening.
The head bolt torque specifications, for a Caterpillar 3024 diesel engine, is 170 pounds per square inch. The bolts should be tighten at 50 pound intervals.
In order to change the torque you will need to tighten the bolt on the exhaust side of the injector to fifty inch pounds. Tighten the drivers' side bolt to nine foot pounds.

If you were to describe a cat in order from head to tail, that would be spatial. I am not aware of a way to describe a cat chronologically. Chronological order is based on time (for example, describing a process in order from start to finish).

Hello: Install cylinder head bolts. Tighten cylinder head bolts according to following procedure: Tighten cylinder head bolts in order shown, Can not show diagram for this. Tightening torque : 36.1 lb-ft (49N
Begin by tightening the head bolts on each corner of the head. Next, tighten the center head bolts. Tighten the bolts on each end of the head and move towards the center.
Tighten from top to bottom and from front to back...80 lbs of torque.
To tighten and loosen Allen head bolts

Many of the newer head bolts are tightened all bolts to a specific torque spec then tighten all bolts another 90 degrees or whatever the manufacturer recommends and possibly even another step. The idea is to tighten in stages so that you do not warp the head.
10 6 1 2 7 9 5 4 3 8 tighten in that order when tightening turn one quarter turn then torque to 65 in that above order and then tighten to 65 in that order again
According to the manual for a EJ25 SOHC:Bolt sequence:____| C A F || E B D |-----B: INSTALLATION1) Install the cylinder head and gaskets on cylinder block.CAUTION:• Replace cylinder head gaskets with new ones.• Be careful not to scratch the mating surface of cylinder block and cylinder head.2) Tighten the cylinder head bolts.(1) Apply a coat of engine oil to the washers and bolt threads.(2) Tighten all bolts to 29 N·m (3.0 kgf-m, 22 ftlb) in alphabetical sequence.(3) Tighten all bolts to 69 N·m (7.0 kgf-m, 51 ftlb) in alphabetical sequence.(4) Back off all bolts in reverse order of assembly by 180° first; back them off by 180° again.(5) Tighten bolts A and B to 34 Nm and bolts C-D-E-F to 15 Nm(6) Tighten all bolts by 90°(7) Tighten all bolts a further 90°CAUTION:Do not tighten bolts more than 90° in total angle
Head bolts for a Punto 60s need to be tightened in 3 stages: stage 1 - tighten all bolts (in the correct order!) to 30Nm. stage 2 - tighten again, in same order as before, by turning wrench a further 90 degrees stage 3 - repeat stage 2
The Honda had bolt tightening sequence begins with the head bolts on each end of the head. Tighten the head bolts moving to the center, alternating from and to end.
Flare nut wrenches are used on fuel lines. Regular sockets are used on head bolts.
Starting from the left hand side on the back of the head 5328 starting from the left hand side on the front of the head 7146 Tighten the cylinder head bolts to 44 ft.lbs (60 N-m) in the order shown in illustration. Use the J 36660-A torque angle meter in order to rotate the cylinder head bolts an additional 95 degrees. Tighten the bolts in sequence to the the specified torque. With all the bolts tightened, make a second pass tightening all the bolts an additional 95°. Remember, 95° is just a little more than a 1/4 turn, not 1/2 turn, or from 12 o'clock to 3 o'clock on the dial. Do not tighten beyond this specification, otherwise the bolts will be overstressed and the gaskets may suffer damage.
