Wouldn't a leakdown test pinpoint which valve (if any) are sticky? If you have the equipment, this might be the next step.

Fuel injector getting the right voltage doesn't mean it is spraying properly. Which cylinder is struggling? The computer should tell you which cylinder is at fault. Was there oil in the nooks/crannies near the filler cap/blow-off hose?

There is no reason to pull the head for diagnosis.

How did you verify airflow is not impeded?
