does anyone have any knowledge of the stage V hemi conversion heads for the 440? I have been interested for a while but dont know of anyone ever actually using them . anyone have any info?

 

From what I hear you should build a big motor or they are a waste of time, they are so big and flow so much it's hard to get into the rpm range with just a 440 unless you spin the hell out of it.
Go to Moparts.com Board index and ask in the "unlawfls race only" board. There are alot of hard core racers there that have experience with those heads. You'll probably get advised to use either Edelbrock, Indy, or Mopar Stage 6's.

 

ive seen alot of guys run them, and have issues...keep in mind that its a head not intended for the block...
