and the lifters to???

The point of cam break in with std hydro lifters was to establish the wear pattern correctly, there is no wear pattern on rollers. You can let them soak in oil like AtomicHoe said or use some assembly lube on the cam during the build.

So I went to do an oil change and the filter I picked up doesn't fit, it's the one the book told me to get. I went with Mobil 1 and it is an M1-201.

yeah, I saw that. Mine is a 4WD which is what the part number goes to. But it isn't as big around as the one that's one there and it doesn't screw on. I guess I'll cross reference the one that is currently on.

I was told that the motor was replaced, I wonder if it was replaced with one from a 2WD
