Features you can see vs stock.Remember the materials springs and valves are made of is supposed to be the best and a big factor in the longer life of these parts.Time will tell.
Titanium Valves have been around for Cdales for a long time. I don't know who makes them, I'm sure if you want a set the site sponsors can dig some up for you. If not let me know and I can refer you to some places that have them.
if TI valves have been around why have we been waiting for kibblewhite valves? are the ti valves not as good or are there problems with them? just wondering if i could have used those instead of waiting so long for the kibblewhite valves?
