This is the scenario:

I am going to be doing some performance work on my 2002 T/A. Being installed is the performance cam/valve springs, timing chain, ported oil pump. I have Redline oil in the sump.

I had intended to change the oil after my swap, but really, the oil has less than 600 miles on it because I didn’t drive the car over the winter. I’ve got practically clean oil in there!

I know that late-model roller cams like those in the GM LS1 don’t “break-in” like the old non-roller varieties, and you don't use an "assembly lube" on the lobes or bearings.

But I’m still wondering about my metals content being high in the oil and about the occasional piece of small dirt from opening the valve covers, front cover, etc.

What are my options?
Should I just change the filter & add another quart after the engine’s been run a bit?
Or
Should I go the expensive route and dump this oil/filter and put all new in?

Change it. It'll get a bunch of the foreign objects from the swap out of your motor

since when is changing your oil an expensive route?
you are talking about the longevity of your engine here.

You should use assembly lube on the cam journals, just not on the lobes. Run the engine for a couple miles to let the oil clean out anything. Then dump the oil after 20-30 minutes of driving and swap the filter.

Interesting about the assembly lube, because it isn't mentioned often at all. One of the sites quoted most often by ppl here at LS1tech for cam install information is LS1Howto.com.
Notice this part:
Are we sure about the need for assembly lube?

We use assembly on every motor and no issues. I am not a big believer in using motor oil for assembly. It's your motor so you have to make the call. 10 dollars for assembly lube or 1.5 for motor oil.
