Harley Davidson Twin Cam engines used Hylift roller lifters till 2001, then went to cheaper Delphi parts. They are NOTORIOUS for lifter noise and several companies make parts to help quiet them down.
I put Hylift roller lifters in mine plus the "rocker lockers" and it turned it from a "thrashing machine" to a sewing machine as far as noise is concerned. Going by memory 4 roller lifters were right at $160 back then.........
