Default Does the valve train need to be inspected?

Looking at a 2009 C6 Z06 with 35K miles. Had the heads done at 20K miles by Vette Doctors in Amityville NY, with WCCH stage 2 heads, cam, springs etc. The cam profile is .678 int/.680exh .239/.241 duration @114 degrees.
The invoice from the seller doesn't indicate which springs where used, I have an email into them to see if I can get more information, but looking to see what people have to say here.
Thanks

As posted on the Corvette Forum, you'll want to have a shop verify pushrod length is correct, and then swap in a fresh set of valve springs that are good to .700" lift. See the link:

WCCH heads are popping up with guide wear already, so I would check them for sure.
