Guy's,



I was wondering what concerns I may have with running mismatched rockers? I'm running a 312 in my 55 which was rebuilt before I bought the car, today I had the valve covers off and noticed one side has the 1.54 ECG 6564 rockers and the other side are the 1.43 575-1066 rockers. So far I've put about 7,000 miles on the engine.
