I just bought a set of hollow stem intakes for my mild L-92 build and there is a 3 page thread of how they break!Anyone have any input on this??Stock G.M. valves..Thanks

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 swapped to GM LS3 hollow valves, no problems on my 219/235 .607/.621 cam.

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

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
