Sounds like typical advertisement to me I'll believe it when I see it, wish we had millions of engines out there testing these. Also I can't find any info about weather or not they sell an MDS version...
They also speak from the point of view that the lifter is the only thing causing the tick, they don't address the pushrod top and rocker seat wear that causes ticking and exhaust bolts break and cause ticking, more so when cold. Lifter failure is not the only tick they have.
Don’t forget the pushrods wear the balls off the top side and the rockers wear the sockets where the pushrods go into,,,,,,, and sometimes the pushrods are barely long enough from the factory and don’t provide enough preload on the lifter.
