I suppose he could've given me incorrect information, but he seemed to be on top of things, and is an Isky support engineer (also mentioned he has these in his daily driver). Am I naive to believe him?

A friend has a set of these in a near 1200 hp 632" Chev been there 35K now with 1000+lb open spring pressure.My set of Isky EZ rollers are in a Donovan 427"sbc 660lbs open pressure on a 440 cam lobe.Should last forever the bushings are pressure lubed.
