[Scufty]

Sorry forgot to add a few things ....The reason ..(and nobody has actually stated it yet) that you need to keep your RPM's above 2000 is so that the lifters will spin during break in ....and I certainly dont agree that "you need to go to a roller setup" No you dont.... You can go to a good ole solid lifter and cam and there is no reason that you should have a issue...
Also you need to change the cam and lifters at the same time of course


Just my 2 cents ..cheers
