DoD Delete and Valley Cover questions I have a 5.3L LMG that I am planning to rebuild. I have found some DoD Delete kits, but I wasn't sure what valley cover to use. I know I don't want to (or can't) use the original AFM type valley cover. The flat/blank looking valley covers I have found don't appear to come with the little O-rings on the underside. Do the non-DoD valley covers need the little O-rings? I have also seen two different types of valley cover seals/gaskets. One is a flat metal and rubber gasket, just like the Gen-3 style. The other is a formed silicone/rubber seal that appears to "stick" in a groove in the underside of the valley cover (kinda like the vale cover seals). I already have an LS3 valley cover that I was thinking about using for a future build. Could I use the LS3 valley cover on the LMG? I'm getting a little confused with all the different types of covers/seals. What is the easiest option here?

I thought the LS3 cover might work. I wasn't sure if it was the preferred cover, due to the PCV tube in it. I haven't even thought about what PCV set-up I'm gonna use. 
I didn't want to buy another catch can kit, because I plan to sale this motor. At this point, there's no way to know how it will be used. I suppose the PCV tube on the LS3 cover could be plugged/capped if it's not wanted. This motor will have the TBSS intake on it, if that matters.

I might have to look into that, because I was kinda wanting to save the LS3 cover for later. I want to build a bigger motor for my Camaro later on, and I was thinking about starting with either a 6.0 or 6.2 block. Most of those come with AFM, so the LS3 cover would be ideal.
If it is easy enough to use the stock AFM cover, then I might try that instead. I did not plan on using the AFM cover, because I heard there were some issues with oil pressure and some kind of filter under the oil pressure sensor....? Like I said, I'm a little confused with these options. I'm more familiar with the Gen-3 motors. This is my first experience with a Gen-4 motor.
