Valve retainer/spring upgrade
I don't have the extra money to do a complete rebuild should I float a valve. Is spending money on Ti retainers and valve springs insurance money well spent? Or is 9# not enough to worry about?
The goal now is to hit 400rwhp on spray and 9lbs boost. This is only for dyno numbers and then will hopefully be around the 340 rwhp(daily) tuned by an EMS. I am, however, realistic in knowing that I will be tempted to use the spray on occasion.
TIA,

Even without boost, I went with the uprated springs and retainers and found that the engine idled much smoother, with less valvetrain noise, but I also ran tighter valve lash

I don't see how more boost affects your valvetrain unless you're revving higher than the OEM 9K rev limit. The stockers should be fine for the life of the engine, they were designed and tested to do just that.

That's the key and why I'm concerned. An owner in my part of the east coast ran the car to 10k and floated a valve. Bumping it to 9500 was a possibility I was/am willing to explore.
