Your manifold/haders will bolt right on. You'll need new center bolt valve covers, new style intake gaskets, and the aformentioned intake manifold. The self aligning rockers can be omited for some hardened pushrods and guide plates.
Your cam selection is limited onless you are willing to replace the springs, I think it was .420 lifft, that or .480...I can not remember at the moment. Call a cam company, they will set you up with exactly what you need.
I wouldn't even bother with junk yards on this...and I'm a cheap b@stard.
As for new heads on an old engine, it all depends on how old you are talking about, and how hard you'll be pushing it. If you have 100K on the clock, I wouldn't even think of it. (not again anyways)
However, if you have 50,000 or so, I think i would yank it, inspect real close, and take it from there.
