A lot of that was some people confuse the "better head" with the "better value." Yeah, you'll be able to make more power with Eddy, but unless you're trying to make more power than RHS is capable of, the RHS heads are the better VALUE (HP per $). When you have someone asking "Which heads, RHS or Eddy?" and their post goes on to say they want a 450 HP street motor, then RHS would definitely be the way to go at barely over half the price of Eddy's. If someone was going for something over 550, then Eddy's would probably be the better way to go. Neither RHS or Eddy are the best head out there.
