I do have the lifters, but I didn't properly order them or label them when storing. I did read up on it a little and was told that I could put in some new lifters, but I'd have to re-break them in. Thoughts?

I'm not looking to get super-long life out of this setup necessarily, since I eventually want to put a built 396 in it, just can't afford to go that route for a few years yet. This car will likely see under 10,000 miles per year, or whatever the insurance cutoff is for "classic car" or whatever that designation is.
