New heads/intake/rear end

@rumble - I had the Crane cam (454/480 lift @ 050, 216/228 duration) in there until last winter, with that cam I ran a best of 12.21 with open headers, 12.50s through the mufflers. After I put in the Lunati 60404, which is a 513/533 lift @ 050, 234/242 duration, I ran some 12.20s and 12.30s through the mufflers. Like I said earlier, I'm sure not how much the heads I have now are ported, I've looked at them but I don't know what I'm looking at and I haven't had them flowed. I figured going with aluminum heads, which are lighter and supposedly flow better than stock heads would be a good choice.
