Do you mean the bolts that go from manifold to engine, or manifold to turbo?

Is the factory spec still valid with a greddy cast manifold?

Tighten it till just before it breaks. Can you actaully get a torque wrench on all the bolts anyway? I just tightened the **** out of it and have had no issues.

Hand torque them inside to outside and then re-torque them in a couple of days. Only one of mine came loose.

I just tightened mine to PFT spec.
