LS7 Valve Train Questions/Concerns

[68sixspeed]

Pretty much right on the head there.... If he isn't covered under an extended warranty, I would suggest checking the guide wear over the winter which can be done in the car. The jury is still out in the 1pc stainless vs stock valves and also how fast the bronze guides will wear out compared to stock. I'm going to give it at least 6 months to see what shakes out.. The info really just came out over the summer on the valve problem so I don't think anyone knows for sure how to fix it or the root cause of the rapid guide wear. Some cars have it, some don't so far. Perhaps some aftermarket castings will be the better fix... I think it is too soon to tell.
