If I HAD to choose b/t those 2 heads, I'd go w/ Edelbrock. Why the open 88 cc chamber? Go w/ the closed 84 cc chamber Edelbrocks if you go that route. Better all around.
Those Stage VI heads need a ton of work to be useable and make decent power from what I've seen. After you've spent more in them than comparable Indys, the Indy head will still make more power.

My honest opinion...I had a set of Edelbrocks several years ago, then swapped them out for Indy SRs. I'd get some prepped Indys from someone like Dwayne Porter and call it done.

I had a brand new pair of Edelbrock performer rpm's sitting in my bedroom when I found a set of brand new Stage VI heads and intake on ebay that had been fully ported for the same price as the Edelbrock's. I sent the Edelbrock's back and bought the stage VI's. At this point after running them for five years I have to say I don't think my car would be as fast with the Edelbrock's unless I put a bunch of money into them. The only thing that bothers me about the Stage VI is the wet header bolt holes.

Agreed on all points .

The only reason to use the eddy open chamber head is because you have a shortblock with quench dome pistons from an open chamber, iron head build.

stage 6's need a lot of work, sometimes they won't even drop on the block dowels.

Talk to Dwayne ...
