Titanium spring retainers

[RustyRatRod]

Here is an example of near disaster I experienced. "Stock class" style cam with .474" lift but with very fast opening rates. Spring pressures were about 160-180 seat/360-380 open with Schubeck/Smith composite puck hydraulic lifters. Other retainers were intact, but pretty beat up. I upped the spring pressures to about 200/400 and the problem went away and valve adjustment remained more consistent between adjustments.

I just had to check the spring pressures between seasons to maintain the "safer", higher pressures.

As for aluminum retainers.....put them in the aluminum recycling bin!

Myron, you were very blessed there.

Don't know a lot about titanium, but do know this. How strong it is & how durable depends on the elements that are alloyed with it. Some T valves have hardened tips because the T grade used for the valve is soft-ish. Same deal with retainers. Wrong grade T, & the v/springs can chew up the retainers.
