Which heads are best

When I first got married some 25 years ago my wife moved into my house and started cleaning out all the cabinets while I was working one day and she calls me and says I set all that old crap that was in the kitchen cabinets out in front of the garage door. Then it hit me that I had a magnesium hemi crossram with carbs and a Max Wedge cross ram with carbs in the kitchen cabinets in addition to a few other choice items. I told her she better get out there and stand next to that stuff till I got there.
