If it runs with good comp & doesn't smoke, you might run as is. If you have to rebuild....54/5 or 6 car heads are better than the truck heads. The truck heads have fat valve stems. Those can be replaced with car valves. Some truck heads have the square under carb passage & can use any intake. if tall & narrow you have to use Hot Heads intake or weld up the part that is above the car intake. Replace draft tube with PCV system.If you keep truck heads you'll need a '54 wet 4 bl intake or drill a dry intake for remote thermostat.

yeah, that number is the '54-55 truck heads. As I mentioned elsewhere they won't fit your Desoto(unless you have a Chrysler hemi your holding out on telling us about!).
