Ok I'm looking at some heads, which would be a better choice for a 2000 6.0 220 cam, LTs, LS2 intake? Found some 317s off a 6.0. Or I found a set of 243s off a 5.7

The 243's have a little smaller combustion chamber so you will get some bump in compression and they flow a little bit better than the 243's.

Ok thanks
With 243s and an LS6 cam(i would go bigger) you essentially have an iron LS2. Defiantly the way to go unless you plan on a crap ton of spray or boost.

Ok thanks
I'm not planning on spray or boost, it's just a budget build, so far I have an 04 extended cab, built trans, 6.0, LTs, LS2 intake. For 1700 invested.
So the 243s r the better option?
Yes

You already have the 220 cam? A 6.0 will laugh at that cam. It's WAY too mild IMO. You could run that cam on the stock converter no problem...oh and 243s all the way!
