M11 bolts: 1st step; - 22 ft./lbs. 2nd step; - turn 150 degrees M8 bolts 9-10: 1st step; - 11 ft./lbs. 2nd step; - turn 75 degrees Note: Do not reuse cylinder head bolts. Do not allow oil on cylinder head, head bolt bosses.
bull on last line.
the bolts are all spec'd wet (oil means wet)
no dry bolts allowed, here.
use Felpro gaskets, Suzuki is defunct , mostly. for parts. (long long waits)
FELPRO ! not china clone parts in the engine.
yes, gasket dry, and both surfaces there dry.
now sealants , there. on gasket,
FELPRO tells you what to do, read it.

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!
