Edelbrock Performer 5.0 Heads
 

I am considering purchasing a set of the Edelbrock Performer 5.0 heads.

I understand that they were recently reconfigured for improved performance.

Has anyone purchased a set of these new and improved heads, and could you comment on them?

Alternatively, has there been any dyno testing done to see what if any increase in performance can be expected ?

Thanks.

I have the old ones. I like them a lot. I have trapped 120 on them:D
