Nothing wrong with stamped rockers other than they are slow moving and don't deliver the advertised ratio. I would never consider them an option on a solid roller set up or anything with a lot of lift.... There are much better options.

A tid bit in support of Paul's comment ?

"First of all, rocker arms rarely maintain the same ratio throughout the entire valve-lift curve because the rocker arm moves in an arc as it generates lift. Roller rockers do a good job of maintaining their stated rocker ratio throughout the entire lift curve, but the same is not always true of stock-stamped factory or budget stock replacement rocker arms. These pieces often test far short of their rated rocker ratio."

..."it's well known that the inconsistencies of stock rockers and the friction and heat they create mean there's power lost with them. "
