    I have no experience with them either way. I think that Neil (Chryco) has said that he would never use Edelbrocks, FWIW.

    with only those 2 choices Stealth or Super Stealth , more bang for the buck using Stealth .
     As I have said before we gained 3 RWHP using ported eddys over ported Iron 452 heads

    Chryco did answer.  Stealth heads are made by 440 source. And bang for the buck I agree they are the better choice.
    Just upgrade the springs.

    Hey Mozz,

    I have got 440 source heads myself. They do not take too much to tickle to go 600 buddy, they are the head to go for bang for buck. :2thumbs:

    Was there a problem with 440 Source heads, or did that go away?

    The prpblem with the 440 source heads is that they come with a cheap set of springs that are probably only any good for a standard replacement camshaft in a bone stock original engine recondition, plus it is a good idea to change out the collets and locks. Depending on how much lift you are going for, the valves would need a change out if going for a large spring pressure in my opinion. :2thumbs:
