| RE: Are Edlebrocks heads that much better |

They do flow much better than either garden variety or CJ heads. The Edelbrocks are based upon medium risers while the CJ and other passenger car heads are a low riser port. The obvious benefits are that they are lighter, flow better, handle higher compression ratios, and have a better chamber design. As to whether those things are significant enough to outweigh the cost or give you a high enough return on your investment just depends on your individual situation. Higher lift cams and stiff rear gears will bring out the difference with the extended rpm range and better breathing but it's also not real hard to make over 400 hp with iron heads. Port flow is not one of the FEs problems.
With the bare heads, yes you can just clean up the heads and use your valves but you're still going to need the expertise of a machine shop since the valve spring heights have to (or should) be set. While not as expensive as completely going through your C6AE heads, it's not free. |
