The best, lightest rockers on the market are stock ones. However earlier models or after fatigue they have been plaged with loosing their bearings.
Harland Sharp has a kit that replaces the trunions and uses C clips to prevent that.
You can send yours to NASTY PERFORMANCE for a rebuilt for around $260 last time I checked.

I have the new dart heads(225). The cam is a 608 lift comp cam. Some articles said something about some rocker arms will cause the knock sensor to retard the timing. This is what i am trying to avoid. But if the stock rockers work that good then i will just save that money and apply it towards something else.

Yes they are out of the box. We did change the valve springs though. My engine builder thought it would be safer to use a double spring that is a little bit stronger than the single spring that comes with the heads.They are going on a 6 litre iron block (370ci) with either a F1c or F1r@ 15-17lbs of boost.
