Are these different than the stock ls3 sodium filled valves? Also the L92 escalade motor valves are solid with no sodium.. Give those a try.

I have had one break, but that was because it was put in a bind when the rocker arm broke.

Default it´s the l92 valves that break

not the ls3 ones
gm had that problem with some early l92 engines in 2007 and it had more to do with the solid valves weight and material and the valvespring
