I'm replacing the valley and intake gaskets. Looks like I had a bad leak and I took everything off and cleaned pretty good.

Just need torque/sequence also while taking everything apart I noticed the knock sensors looked rusted should I replace?

And there wasn't any silicone used on old gaskets should I use any?

Any tips I would appreciate

Here's a write-up that you'll find useful for the torque specs, etc: http://www.ls1howto.com/index.php?article=18

No silicone is needed for the intake or valley cover gaskets. If you've got the valley cover off, it's a great time to just upgrade to the '04 LS6 cover and ditch your pcv.

Anyway, I used the instructions posted above from LS1howto.com.

As for those knock sensors... if they can be cleaned up, I'd probably try that first (especially if you're not getting any codes).

Any idea on how hard the 04 cover is and what's needed (write up)

There is also a write-up on LS1howto about it, but it is using the '01 LS6 cover (which is now obsolete unless one WANTS to run an external PCV valve).

Here's a link to a thread that I posted my response when I did my conversion: https://ls1tech.com/forums/generatio...y-cover-5.html

Thanks again, ill be working on it this weekend. I'm thinking for now ill just keep stock valley but what's your opinion on catch can?

Is it better to install catch can with stock PVC line or do the upgrade and than instal catch can?

A good catch can does a pretty good job of keeping oil out of the intake with LS1 PCV system. The newer LS6 valley cover aids in letting less oil in to the intake so the catch can may not be needed but all cars are different so the amount of oil varies. If I were you I would put my plans on hold temporarily and order the new valley cover while the intake is off.
