Prices are from GMPartsDirect.com, but they have changed some since the original post. Notice the date. I've found that after shipping, SDPC carries all of the LS7 parts for less than GMPartsDirect.com.

LS7 Exhaust Valve: about 5.225"

I hate to question the info of such a knowledgeable member, but it seems the overall length of the valves would have to be much longer than this for such a high port head?? Can anyone confirm that the 2.20 LS7 valves are only 5.185" long, and not maybe 6.185"? In comparison, a set of High Port 12 Degree Gen1 SBC heads uses a valve length of 6.240". Also, are the LS-7 stems 5/16 or 8mm? Also, did the price of these really near double in the last year? Has GM offered them in a quantity of 8 set at a discount like they do on all other "per cylinder" performance parts?

I would double check the length of the valves, but they are in thr car right now lol. The stems are 8mm, similar to LS1, LS2, and LS6 vavles. The price on the titanium valves did go up a lot. But it's possible to find used sets for much cheaper. I think many LS7 parts are on super backorder also.
