The prop valve probably had more effect on your rear power than the drilling.

My understanding of drilled drums was that it's only beneficial in applications with high heat and heavy use. you don't typically see a drum glowing red hot

Watch for cracks, that cast iron can get heat spots really quickly. A drilled rotor is typically internally vented and has extra structure to prevent cracking where as a drum does not.
