    Are there any bolt-in upgrade rockers that would provide any sort of power/efficiency improvement? Roller rockers and/or more lift? For a 98 4.0 OHV

    Valve covers are leaking anyway!

    This thread should apply

    M90 rebuild (rudy)

    I'm not sure if it is as easy as bolt in but it sure looks purty.
