Intake Manifold Question

[Adger Smith]

Way to go SS Div 6. That was good. works ever time as long as no one has cut it before you. I use those very same formulas. Pay close attention to the angle of the head @ the intake surface. Remember it is better to make a couple of trips to a shop than have too much cut off by making a rough guess. I tell customers up front that they might be back for more. You can make a rough guess by looking down the bolt holes & see how much they are off center. You can also measure from the center of the right bank intake bolts to the center of the left bank intake bolts. Then flip your manifold over and measure the bolt holes on it. Then cut the the manifold or head surface the 1/2 difference of the two measurements. Be sure to use bolt holes that are mates. Some maniflods dont have in line bolt patterns. You can also use this same method for a quick check of port alingment.
OK FED, how is that? :~)
