Best head for the money??

I like the 346 if you're talkin about factory heads. It's been reported that they have the 906 intake port and the 452 exhaust port. Sorta the best of both worlds.....but honestly, you're not gonna feel a difference in the butt dyno with any of the iron open chamber heads. now if you are including aftermarket, the 440 Source Stealth heads are a pretty good bang for the buck.....that is considering you understand they will need working to reach their full potential.
