The only sane way to disable VVEL is to replace the heads. VVEL is an oil-pressure-driven mechanical system with an eccentric shaft, etc. The electronic servo just controls the angle

Have you gone over all the basic maintenance/inspection stuff? PCV system, air filters (not clogged, not leaking air around them from a bad seal, etc?), clean the MAF sensors, reset the idle air volume, check for exhaust / intake tract leaks, etc. There are a lot of "little" things that can adversely affect engine performance.
