Interesting that the article mentions lifter galley oil restriction and windage trays should not be employed during cam break-in. Along with faster rate aggressive lobes, increased spring pressure and higher rocker ratios, getting all the oil splash you can makes sense at least in theory. Also, we all have read of removing the inner spring of duals but some say that may not be enough, that installing lower ratio rockers during break-in also should be done. Who does or doesn’t do what when they break-in their flat tapper cam? (old slow lobes or faster aggressive) Feel free to opine.
