With solid rollers, I worry about shedding those little needles in the engine like my friends used to do, unless you run bushing lifters like Isky. Plus I've gotten lazy these days about painful lifter adjustments (I always did mine hot) and just stay away from the redline. That, the usual adjusting, and shaft rockers all make the girdles less desirable unless you go for locomotive valve springs. SS rockers are bullet proof as are bushing lifters, and T&D are just a few miles from my house.
