There is a sequence of tightening the head bolts in a specific order in 2 passes, the preferred method is to tighten all bolts to 22 ft lbs, then add 75 degrees turn to long bolts, 65 degrees to medium bolts, and 55 degrees to short bolts. If you need the picture go to a library and use alldata to print it out.

Correct pressure for torque the head of mazda pickup 1998


Since you didn't say which engine you have, I've pulled torque specs for 3 different engines. Also, since I can't include a diagram showing the relative locations of the numbered head-bolt locations, it would be a good idea for you to purchase a vehicle specific repair guide that will show this info.


Take particular note about the TTY (Torque to Yield) bolts used on 2 of the 3 engines shown. It is said that new head bolts MUST BE USED when head is replaced or re-installed to obtain the proper torque.



B2500 4 Cylinder

Torque sequence: --------- ' 10 6 2 4 8 ' front ' ' ' 7 3 1 5 9 ' -----------Step 1: torque in sequence to 51 Ft/Lbs Step 2: torque again in sequence to 51 Ft/Lbs Step 3: final tighten all bolts an additional 90 to 100 degrees recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) that permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.







B3000 3.0 6 Cylinder

Torque sequence ---------- ' 6 4 2 8 ' ' ' ' 5 1 3 7 ' ---------- Step 1: torque to 59 Ft/Lbs Step 2: loosen in sequence (1) full turn Step 3: torque to 41 Ft/Lbs Step 4: torque to 73 Ft/Lbs









B4000 4.0 6 Cylinder

Torque sequence --------- ' 5 1 3 7 ' ' ' ' 6 4 2 8 ' --------- Step 1: torque cylinder head bolts in sequence to 26 Ft/Lbs Step 2: torque cylinder head bolts to 56 Ft/Lbs Step 3: turn cylinder head bolts in sequence an additional 90-degrees recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) that permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.


Good luck with this job!

Hi, I neeed to know what the torque pattern is for


If your installing a new head gasget, the torque spects and pattern will come with it. If not and you are installing a new head gasget you have to use new head bolts, the short bolts witch go in next to exhaust manafold are 43 ft. lbs. and the longer ones in the center of the head are 46 ft. lbs. start with the one in the middle by exhaust and next one in center of head next to it and do the rest in a circle pattern, after you got them all torque than you have to turn each one 1/4 turn, thats why you have to use new bolts that 1/4 turn stretches the bolts. If you don't understand this go to auto zones web sight thats where i found it. I just did one 2 weeks ago.

I need to know how much pounds is apliied to a 350 chevy cylinder heads


What is the year and model of your vehicle?

On a 1968 Chevy 350 small block it is 60-70 ft/lbs with sealant applied

When torqueing the heads, it is helpful to start at around 25 ft. lbs. and torque all the bolts, then go to 50 ft. lbs., and finally, your specified torque. Doing this in increments will help give a nice even torque to the heads

I need the torque specs and sequence on a 1998 chevy 350 vortec


Vortecs are a little different that old school small blocks, grab a Haynes or Chiltons, the cross patterns and specs are simply diagramed. Vortec, as any really, start with 25# then 45# and then final torque which I believe is around 70-75# but to be sure verify with the manual. AutoZones, Murry's, Adavance auto all carry the books, Cheap insurance.
