I would torque them to specs, but you wouldn't want to remove the head again. Years ago it was common to have to retorque head bolts after they went through a warm-up cycle. Typically that isn't necessary any more, but in your case you want the correct clamping force to promote proper sealing.
Be aware that a lot of imports call for replacing head bolts. They are "torque-to-yield" design in which they stretch when tightened, and using them a second time is not recommended.
