Actually I was mistaken about the "third" spring. It was dual spring with a "damper", a typcial application for both rollers and flat tappet.

My roller had about 8,000 miles on it but I think what "pushed it over the edge" was ME! I didn't have specs for the valve settings and thinking a wider gap is better than being to tight on the lash I set the lash TO BIG.

Turns out those little rollers don't like being "pounded" and correct valve lash is crititcal with a roller lifter. Never the less, no rollers for me ever again (UNLESS I'm going drag racing only).
