Indy LA-X vs. Eddy heads

Has anyone done a comparison dyno between these heads? I am still reading up on info for a 360( possible 408 ) build and was wondering about the pros/cons of using one vs. the other. I know the Eddy heads probably weigh less but was wondering if the the LA-X heads might be the better bang for the buck?? Of course with 2.02 valves the LA-X heads are 1075 assembled so there is not a huge price difference.
