Eddy Heads: Like or Dislike?

I just ordered my edelbrock rpm heads for my 318 which i have rebuilt with the kb pistons so with the heads it should put my compression ratio around 9.5:1. I was just wondering what others think of these heads. Anyone install em and if so did you notice a good gain in power? or did you have any problems with them? what did you like or dislike about them? Thanks for any input. -Kory
