BTW,

If you're wanting to spin to 6500, you can do it with a hydraulic roller...that will save you from having to run with the risks of solid roller lifters. Longevity and a solid roller really don't go hand in hand. Spring pressures have to be checked occasionally (depending on the cam grind), lifters have to be R&R'd every 10000 miles or so, etc.
