Default Can anyone ID these part #'s

I bought a set of "Corvette LS1" valve covers off of ebay but they don't have the same pcv/hose configuration as my 2000 LS1.

The part #'s are 12570696 and 12570697

Mine are 12559895 and 12559892

I've check the F body LS1 and they look identical to the 2000 Y body LS1. I've also seen a truck LS1 and the pcv hose didn't match these either.

Maybe Z06?

my friend came over yesterday to show me his C5 with his new 427 in it and he was showing me the Z06 valley cover setup.

Now I know how to convert it, thanks for the link.

This would explain why the pass. side cover only has one PCV pipe.
The drivers side though does not have the PCV port blocked as in the conversion but a small 5/16" pipe like on the other side.

any link to LS1/6 part #'s?
