Keine Ahnung hab noch nicht versucht LS7 Ventile einzuschleifen,nur von Motorrad und Mercedes Motoren.
Der M110 in den Ende 70er jahre 280E Mercedes(185 PS) ,Doppelnocker die wellen liefen gegeneinander brennraum hallbkugel also optimal.
Der Motor hatte schon Natriumgefüllte Auslaßventile.

The valves are not the cause.
But it's your car. Mod how you feel you must. But there's a price to pay for being wrong.
GM made them stronger in 2008? Link? Any data at all to back that up?
OP is in GMs pocket and as such can't openly speak on the issue. If he could he would release real spintron testing with heavier springs and SS valves, he also would release his promised findings about valve guide wear. The OP would never take a stand against GM that much should be obvious.
Ich weiß net der ganze LS7 ist mir net geheuer,mal einfach so 250.000 km abspulen nur mit ölwechsel wie beim lt5 ist wohl net eigentlich war mir das klar.
Um ihn Original zu lassen hätte ich auch nie nen LS7 gekauft, der ganze Tuning Kram für LS und LSx Motoren ist verdammt günstig und verdammt schnell zusammengebaut.
Köpfe runterbauen ohne steuerketten zu demontieren wo gibt es denn sowas noch.
