To each their own, but if it were me, I'd probably have them bolted on and be driving the car again by now.

 

That's another way to look at this. Other than the one questionable retainer, they probably would've worked & performed just fine. The surface grinding at the spark plug would not affect performance.

 

An email has been sent to the vendor seeking their comment on the issues. I hope to have a response today.

As far as the LS6 springs and retainers: Yes, an aftermarket cam is on the shelf as are a set of BTR springs and retainers. But, this thread isn't about that - I've got a build thread for those discussions.

 

Mike was called an adult.....1st time for everything. J/K

Hope it all works out for you man.

 

*****.

The vendor and I are going to continue to work on resolving to the matter. More to follow... or not.

 

Best of luck on getting everything straightened out . . . I'm watching to see the final outcome of this, as I'm right at the point of starting to purchase parts for my project.
