I see PSI springs pop up in more than a few of these wicked screaming builds. I was going to run the ML1511 on my L92 build but they're only good to .600 and Im slightly over that with my cam. I REALLY wanted to run the duals like you but the dang VVT phaser is sensitive to higher spring pressures so I ended up with the PAC 1518's

Regardless that engine truly sounds effortlessly comfortable at 7500 RPM

Great job

How's the long term reliability of titanium valves in a street motor??

We are changing the lifters as one Morel was not pumping up anymore and will follow-up with an update on how the valves behaved...

Factory LS7s have Ti intake valves with no issues. I've never heard of anyone with an LS7 having any issues with the Ti valves. Boosted, n/a, etc.

I'm selling my LS7 heads with the Ti valves.

Ls9 comes with a Ti intake valve as well.
