Default GM valve seal part number??

My heads are going to come completely apart while the shortblock is being rebuilt. I might as well change the valve seals while everything's apart awaiting the 918s. Anyone have the GM part # for the stock LS1 valve seals?

My local GM dealership wanted $21.95 for EACH valve seal. I ordered the kit from Thunder, $16 for the whole set.

That's ~$21 for everything. Genuine GM parts. Anyone know what brand the TR seals are?

I just checked the part #'s on the computer at work (I'm in parts at a dealership) - intake kit is $15.74 and exhaust kit is $17.12. That's full list price too.
