Roller rocker arms in a street engine

Although it's not the same engine, the principle is the same: Ford used Crane Energizer pedestal mount aluminum roller rockers on the 93-95 Cobra engines from the factory...I bought the heads from one with 124k miles, and I used them on a blown 5.0 for about 5 years and 20k miles with absolutely no issues. That being said, I'll echo what a few others point out, make sure you're buying quality components and using the correct mating parts. HS and T&D make excellent grade engine components, and if the RPM level, and spring pressures dictate the use of them, I'd use them in a heartbeat and not look back.

Just my .02...
