2005 merc 150 xr6 head torque

[goodwrench63]

My brother-in-law had mice get into the bottom two cylinders over the winter. To make along story short he pulled the heads and cleaned everything out, ran it on muffs and put it on the water all good.... now he's called me concerned about torquing the headbolts properly. Do any of you guys know the torque spec for these? I'm guessing 35 ft lbs but i hate guessing.

Doesn't it say the torque spec. and torque sequence on the cylinder head? You used new head gaskets, right?

only sequence is shown - no torque spec!
