Lucas oil treatment is a viscosity index improver, it makes the oil thicken under heat. All that will do is drive your oil pressures unnecessarily high and very likely reduce oil flow which could have much more negative consequences. Lucas is best left on the shelf at O'Reilly with all the other snake oil. It has a use case but this ain't it. New seals for sure, new guides for sure. The problem will slowly get worse but you have a little time so I'd save up your sheckels in the meantime and see about grabbing a set of used PI heads and having those freshened up or go the full 9 and snatch up a set of Trick Flow heads. They're not cheap but they are the foundation for a helluva little build.
