Hello Priobe
May I make some points of consideration.
First of all I do not advocate any brand or detract from any brand. I have used Dove, Erson, Precision Oil Pumps, and T&D. I have not had any problems with any of them that I believe was attributable to the rocker arm itself. But the problems I have experienced are relative to two things. (The below is pursuant to high spring pressures. To quantify 250# closed and 620# over the nose.)
1. If the lash adjustment screw is screwed where more than two threads are below the body of the screw hole this will put excess leverage on the body of the rocker arm thus causing breakage. Make your pushrods to the length to accommodate this.
2. Pushrod whip. If the pushrods are not stiff enough then when they whip this puts tremendous load on the rockerarm during opening ramp excelleration.
3. When using Dove rockerarms I change the adjusters to ones supplied by Smith Brothers for Chryslers that have a 5/16" ball. Changing your pushrods to work with the 5/16" ball also lets you move the pushrod cup closer to the rockerarm.
I hope this helps.
