New heads/intake/rear end

On heads, If your not going to fullu port the X head, which I beileve would be cheaper, MoPar has the Comando head. It'll use standard rockers and will port out very well. Better than the X head or Edelbrocks.

The LP comando or Indy head is alot of head for a 360 engine.

Jeg's has the small port Commandos - bare - for $850 EACH. That's like $400 more than the Edelbrocks, which comes with springs & valves and such. Are they that much better?
