modern 5.2 FI roller engine cylinder ridge ?

I maybe able to get a FI 5.2 roller engine and the A518 for free. This engine has a ton of miles on ,over 200,000- maybe 300,000. I've heard the due to the higher nickel content used in the modern blocks...that cylinder ridge problems are not that common.
Don't want to haul it home, if there is a good chance that it will be junk.
