Hello. Im new to the forum. I have a 1956 Fairlane club sedan 292 (EDB) and it has been sitting since 1983. It had several stuck valves and the seats were pretty rusty from sitting so long. I had the heads (ECZ-B) rebuilt with stainless valves and hardened seats and when reassembling them I noticed I have one rocker arm that is different from the others. All but one are the 5751066 standard lift and one is an ECG6564B2. Will having one higher lift rocker cause any issues or should I try to find a standard one to match the others?



Thanks,

Bill
