    Rated 5 out of 5 by from rockers Have used several sets of these rockers on SBC's (pre LS). The only issue u may have is with the poly lock. Some OEM setups will not have enough threads for the allen lock, so just use an oem lock nut.

    Rated 3 out of 5 by from Mostly good, 6.25% Failure Rate 1 of the 16 were not sitting right during assembly, further inspection showed a burr on the push rod seat. 1 out of 16 is a 6.25% manufacturing FAILURE RATE. Because I had little time, I used a carbide to deburr the part and was able to use it. I expect much better quality from JEGS, especially when they put their name on the part.
