If you aren't building a race engine those rockers will be fine. If you are making less then 400HP and not revving up around 6000 RPM or higher you don't need fancy aluminum race rockers. When was the last time you heard of a factory motor tossing a rocker arm? In fact I had the fancy $700 rockers on the T/A and tossed them for stockers cause they worked better. The roller tip reduces friction and the 1.6 increases valve lift. You could probably see 10-15 RWH from and not break the bank. I agree they aren't "As" reliable as a $400 set of race rockers but they would be fine for a streeter that sees the track IMO. Also check to make sure even though they are a "self aligning" type they may require screw in rocker studs and guideplates.
