Titanium spring retainers

Yes it frees up power but to me it's about inertia, the lighter the valve train component the easier it is to switch directions in its motion a heavier part has more inertia and will want to keep moving in the direction that it sent, as you lighten the components to that transition seems to be more stable and easier to control! I know all you engine builders know that but I thought it was worth mentioning. Steve Dulcich preached that back in the day and I'm a believer, along with good springs good strong useful RPMs have been achieved in my 340s
