Which Head Should I Use?

It's really a personal opinion type thing IMO. I hear the drool tube heads are lighter, which is slightly better if you're into shaving pounds, but it sounds like the peanut head isn't as troublesome when porting/bigger valves. Oh, I think the tube head has a wider selection of spark plugs, but I may be wrong. Also, I've heard you can remove lifters on the tube heads without removing the head? I've only messed with later peanut heads, so I couldn't tell you much there.
