The LS series are built really well. I maybe would pull a valve cover it inspect the amount of slug and that's about it.
They have a lot going for them for a bunch of reasons.
The Air Fuel ratio is almost always perfect, avoids washing down the cylinders.
Rings are low tension rings.
Cams are roller and do not typically go flat. (DOD is and exception)
Oils are much better than they used to be.
I have one in my Silverado with 178K on it and it still doesn't use a quart, of oil, between changes.
Good advice, get it all. Down to the air cleaner. You will not regret it later.
Cheers.
