Where would be the best place to drill for the probe?

Thanks

Id go position #4. It will give you a good average across the cylinders. Cylinders #1 & #6 will be the richest/hottest. Something to think about if tuning for max power.

# 4 is the best place for it.
All cylinders should be the same, if the injectors and compressions are up to spec.
You can't apply the principals of a carburetted petrol engine to a fuel injected diesel engine.

It's not the fuel that will be variable, it's the air. Due to the log style intake manifold, the cylinders furthest from the throttle body will get less air than the others, leading to a rich condition.

Real world testing shows otherwise. Large tapered plenum can combat this
