Guys,
I know we have beat this subject to death but let me add my perspective to this.
There is a solution and is proven to work as demonstrated by the results over the years.
My dads (Professor Rock) ceramic based coating on lifters (and cams) has been used for years and is an effective solution to this. He can supply Topline Johnson Hy-lift lightweight solid lifters (Made in USA) coated with a ceramic based low-friction and wear reducing coating.
Want a recommendation? Ask Chris at Bullit about him and the coating and how effective it is.

Thanks, just offering the solution.
