hey guys i just bought an 89 lx with a 306 with roush 200 heads and a 526/532 lunati cam. My question is that the roller rockers are very noisy so I pulled the valve covers to check and see whats going on, and well i found the following. The car has Erson 1.6 roller rockers, guide plates and they are stud mounted not pedastal. Well i have had bad luck with keeping stud mounted roller rockers quiet. Can someone explain to me the proper way to adjust these? And please dont say live with it! I will put stock steel rockers back on before i listen to this much longer! When i bought this car it had turn downs on it, and he said that the rockers were a little noisy cause of the thin valve covers, but i doubted that! But i liked the car so i got it. I put tailpipes on it and i love the way it sounds and it runs strong but its too noisy! Please Help!! Thanks in advance!
