Question about valve covers?

I bought some valve covers off of ebay and when I got them I ran the part number that was underneath the cover.

12561823
and
12561821

I cant find them on GMPARTSDIRECT.com

Are they off of a 2000 Z28?

Any ideas?

Thanks

all you need to know is if there centerbolt or perimeter. center bolts work with any head 99+, while the perimeter bolts only work with 97-98 806 heads.

I think there are two diferent styles of centerbolt valve covers ones for our cars which have 2 tubes on the top of pass side and truck centerbolt which only have one breather tube on the pass side
