SOURCE: 87 samurai bolt torque specs for engine

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
