You will better off if you find a set of late 63/ '64 heads for the 361/ 383/ 
413/ 426 wedge or first series 440 that have six bolts to hold on the leakie 
valve covers rather than the super leakie four bolt series that you have.  
Also the newer heads have better flow spec's than yours so the mpg and other 
stuff is better.  The last set of heads that came on 400'sand 440's have the best 
of the flowing and cooling.  They have a casting of 4006452 on them.  If you 
feel the emails don't match from other Imperial people call 1-248-969-1690 and 
ask MoPar Performace the same question.

Why purchase roller rocker's ???  If you want internal engine power have the 
heads ported ( # P 4120437 ).  If you do this, the rollers will show their 
stuff.  And it is an cheaper expense for the power gain.  I wll save ya or any 
other 413/ 440 owner a ten buck bill if you port.  Just email me direct.

Your car weighs a bunch of pounds and trying to do as the 440 into the Dart 
gangs does not make a very happy Imperial driver.  You must built and set your 
engine up for torque.  Bottom end and mid range is your target, nuthin more.
