How critical is the torque setting? Other than the outside two bolts, there's no way to get a torque wrench on them. Guess maybe I can "feel" the outside two and then try to replicate the middle.

Need a little metallurgy lesson. My "new" manifold had a different size port for the wiper vacuum. Need to hit the hardware store for an adapter. Will brass be compatible with the cast iron?
