Anyone have any suggestions of how to measure the angle of the intake port deck vs combustion chamber deck (or any other reference point for that matter) while the heads are installed?

Just needing to verify the geometry of the heads are the same, and would prefer not to pull them.

 

Give us a little more info on what you are trying to do.

From what I gather you have the heads on the engine and you are trying to compare the angle of the intake port face against another head. Am I warm here at least?

 

Actually, I'm trying to verify the intake port deck angle is the same on both heads so I can determine if my intake manfold or heads are off. One of the two is off causing the left bank to run lean.
