The Eagles are my favorite head for the Hemi Platform. They've for a tight chamber, a reasonable sized intake port and the D-port exhaust from the 6.1.

They've done amazing things on a 426 in 4600 lb raceweight cars (I don't know if you can really call 4600lbs a raceweight lol)


The 6.4 head is a more modern version of the 6.1...Not to say the 6.1 is "bad" but I think big ports and peaky power are the norm now of days.

Each head has its purpose. If you're starting from scratch, there is no reason for price or performance that you should start with anything but BNIB eagle or apache.
