These lifters are designed to eliminate lobe and lifter wear caused by inadequate lubrication at the cam and lifter surface. With today's high-rpm, high rocker arm ratio and high spring pressures, cam and lifter failure is at an all-time high.

I went this route on my personal build for the same reason. The thought of Chinese needle bearings improperly hardened, flying around in my new engine was keeping me up at night! Saving over a grand between cam and lifters doesn't hurt either. If you only need 500-550 HP, I don't see the need for roller lifters. Use good oil with lots of ZZDP though of course.
