I'm no cylinder head expert by any means, but I believe the Brodix heads are definitely a upgrade compared to the Eddy's. With that said, and hopefully understanding what you're trying to accomplish, i'd stay with the Edelbrock's at this point. I know you don't want to spend $$$ for bigger heads down the road, but even if you decide to build a stout short block later on, the Eddy's can be ported to make as much power as most would ever need shy of a full on race engine. I guess my thoughts on this are, the stock flowing RPM's are fine for now, and they have a lot of potential if/when you decide to move up down the road. While not cheap to get on the engine, I think they would be a good investment.
