It seems the only issue now is maintaining speed and loss of power

Oil likely clogged something: MAF/MAP sensor, idle air control valve, EGR valve, etc. You just need to check and clean everything. BTW, oil appearing in the air filter area is more likely caused by a defective PCV valve and maybe a little blow-by from worn piston rings than a damaged head. Maybe cleaning the PCV valve and an oil additive is all you really needed.
