pulled out a damaged cam and I am trying to ID it before i put the replacement in. Numbers stamped on the end of the shaft are. 586 RBC 4 H204 H.4.5 (followd by a circle with the letter M in it) cam carries the same casting numbers as I TA 413 cam I purchased to replace it. The 413 seem has about .021 less lift on the exhaust. intake is abut .002 less. just using claiper to get dimensions i have not started to degree it. what will main difference be between these two with respect to performance.
