correct part number for ls6 valley cover?

[nathanWS6]

i'm confused as to the correct part number for the valley cover. every post on gives a different number than what LS1Howto.com gives in their write up.
is it just a different number for the zo6 than the camaro/trans am?
thansk for your help.

The numbers have been updated since LS1howto did the thread.

ok so number 12577927 is correct? number 12568002 shows as a valid order number too..

[SMWS6TA]

Yes Part # 12577927 is the one I got.


Also plan on doing new knock sensors. If you've never changed them now is a good time.
