Heads are an "it all depends" question... Depends on the numbers on your cam - depends on the static compression you currently have and what you want to end up with - depends on what kind of motor you're trying to build and what tranny you're running and rear end gears and tire diameter...
If you get everything matched RIGHT - you'll have a screaming fun to drive package... but just buying "heads" without a lot of other stuff factored into it - can give you a lazy zzz motor with kool parts that doesn't work worth a damn.
For instance --- My (sold it) 56 Nomad was 4032 pounds - ran a 26" tire - 700r4 with a 2800 stall converter - 3:73 gears... a 408 ci Dart Block with tiny little Dart 180cc heads.... It was/is the best motor I've ever had in a car. HUGE torque right off idle - shook windows and set off alarms - and would idle perfectly in traffic etc. Made 550 ft lbs of torque at 4600 rpms -- and 525 hp at 5600 rpms. My point is that the car needed torque because it was a big fat heavy pig ---- and since it was a street hot rod -- it needed to be fun to drive at street speeds. If you're building a race car / street car - then you might need a completely different combo...
