edelbrock vers mopar alluminum heads
To put it bluntly the W series rules all that said unless you're balls out racing a set of Eddys will be just fine (it what is on my 340). But if you want more than eddy and don't mind cast iron try the RHS head (will out flow x heads all day) or a set of W2. Hell the more I think about I might switch to W2 myself, just not sure yet.
