I've got the Endure-X lifters in my small-block Ford. They've worked great for over 6 years, about 10,000 street miles, and a few hundred drag and dyno passes. About .630" valve lift, shifting at 6800-7000. I had the transmission intermediate shaft snap during the 1-2 shift, and my tattle-tale tach said the motor zinged to 9100rpm - that was about 2.5 years ago, and they still work fine.
