I think the KE oilers are a great idea and definitely can't hurt that's for sure assuming installation, plumbing etc is A1. My personal position would be is how you have a tendency to run. Wot for etended periods without question. On and off the sticks and not racing then.... I would imagine they would certainly extend valvespring life regardless. I looked into installing these in 496's.

Plumbing for my set up would be easy. My Eickert thermostatic filters heads have the multiple ports to plumb everything.
