How big is the camshaft??
brainski B. If th camshaft is almost a stock size, say under .500" ,TOTAL lift I stock setup with good end supports for the shafts will work fine. You should get the ARP stud kit for holding the shaft assemblies in place. If money is not a problem, Fine someone one sell the older Erson kit. The only thing that may need to be done is checking for the correct length of the pushrolls. You want the roller to sit on the middle of the valve if possible. I have no info on the new Erson setup and have run a set for 5 years and have no problems with a .600" lift camshaft.
I would tell you to stay away from aluminum body rockers without bearings or bushings where they ride on the rocker shafts. Most important is getting supports for the rocker shafts that extend to both ends. Most breakage of shafts happens at a hold down hole. The support end does alot better job of keeping the assembly togeather. If you do an oiling mode to the rocker arm assemblies, DON'T go any smaller than an .080" size hole to each rocker assembly. This is for a street motor.
If you have a chance could you get a couple of pictures of the broken setup. Like to see what happened. Looking for blueing or just plain failure of a part. Rick L.
