So you're at ~0.24mm clearance on intakes already? If so, I can't imagine overlap reversion being problem as it ran fine from factory with that setting.
What are your individual exhaust clearances?
Now timing of cam-lobes is critically important as well. Worn or mis-adjusted cam-chain will retard cams and result in later intake-closing. Engine should scream and rev like banshee in upper-RPMs with this mod (be more like pre-gen). But again, I can't imagine how Seafoam will affect this for better or worse.
