MM 600 Head bolt torque?

[IDsledding]

I am replacing the pistons on a 98 Mountain Max 600. Anyone know what Ft Lbs or Nm the head bolts should be torqued down to? (I'm guessing somewhere near 18-21 ft lbs.. but not sure)

I also have to pull the reed cage to swap them onto a new cylinder, anyone know what they should be torqued to?
Thanks!!

Thanks!!! Do you know if Yamaha has a specific torque sequence as to which to tighten first?

A criss cross works best.
