I was thinking of runnin titanium valves in my L92. I heard not to run them on the street cause they beat up the seats cause the valves are hard. Anybody have any experience with titanium valves and some miles on their motors who run them so I know if I will run into any problems? thanks guys.

Titanium is actually soft. I don't know exactly what material they use in the LS7, but you usually need something like copper-berrylium for the seats for two main reason: to help absorb the heat out of the valve and to be the sacrificial lamb of the two materials. It's cheaper to replace seats rather than titanium valves.
Put the money into the rest of the valvetrain, or on better heads. Unless you are gonna turn a lot of RPM, you really don't need them.

With the right parts they work, they are on cars with 100k mile warranties. I chose to go with the LS3 intake valves (87g) instead of the L92 valves (106g). I made a thread....https://ls1tech.com/forums/generatio...omparison.html
I rarely see 7k though.

I run the stock LS7 intake ( read: GM) valves on my car and delwest aftermarket titanium exhaust valves in my LS7 heads. I had them ALL PVD coated for longevity. Richard at West Coast cylinder heads provided the valves ( $800 a set) and the PVD coating ( $560 for all 16).
LPE installed them in my reworked LS7 heads. 1,000 miles no problems. I had Richard PVD coat my Stock GM Ti intake and Ferra SS exhaust valves on my last set of heads. They still looked new after 7K miles and are for sale.
