    50120 is rated 4.0 out of 5 by 3.
    Rated 4 out of 5 by from Excellent fit and finish Converted L98 center bolt to perimeter bolt covers but can be used vice-versa. O ring for sealing is a nice touch and very welcome. Used stamped roller tip rockers, question whether there would be clearance for aluminum full roller rockers. Might need slight grinding for those. Cost is worth it.
