Which engine?
It's the USA model
2006 suzuki forenza head
ethan is this a hyjack question?
ethan the car is sold world wide and not just one engine is there, and nobody can guess
but I can RTM I can read the factory service manual in 3 places in USA for USA spec cars.
sure can here it is.
also learn what TTY means torque to yield.
they are bolts that can only be used 1 time.
most failed heads (2nd time) is caused by wrong installation steps, (facts) or parts
quote USA head. 2L
" Cylinder head bolts.
Tighten the cylinder head bolts gradually and in the sequence shown.
Tighten the cylinder head bolts to 18 ft. lbs. (25 Nm) and turn the bolts another 3 turns of 90 degrees using the angular torque gauge KM-470-B."
2.0L(1988cc) DOHC. USA only. answers.
the bolts are in fact TTY.
use once only !!!!!
Id use Felpro set
FEL-PRO ES729061 {GS33473, ES72906-1} Set

it is not your fathers Oldsmobile (lol)
1 clue, (pro) measure head warp first.
if out of spec, stop and fix that first in a real machine shop, (heat relaxed and milled flat or it repeats><< see seen on overheated engines, endless.
sold by other names same car 1.4 and 1.6l too.
but I bet is 2L
and is TTY.
In South America many suzuki there too and all with different engines.(options) for better gas mileage and no EPA blocking engine there.
seen them and drove them.
use a new felpro gasket and new TTY bolts
and allow no head warp, we measure it.
ask how.

The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.
The factory service manual is the only way to go.
Head bolts - 46 - 50.5 lbs (there is an order sequence for the bolts)
Intake & exhuast manifolds- 13.5 - 20 lbs
Flywheel - 41.5 - 47 lbs
Clutch cover - 13.5 - 20 lbs
