Multiheaded Template

[maggot]

On the Wizards site there is a multi-headed template (http://www.wizards.com/dnd/article.asp?x=dnd/mm/mm20020621a). I'm pretty sure this is for 3.0, but it will work in a pinch for 3.5. But my main problem is the CRs the thing generates. Way too low. A eight-head gives you 7 extra attacks, +14 hit dice, +14 CON, +7 natural armor, and +14 on spot, listen, and search. All this for +4 CR.

And it gets worse, the pyro version of the template does appear to increase CR, but gives out a bunch of breath weapons. An eight-headed pyro orge would have eight heads that can breathe fire for 3d6/head, all for CR 6?

Anyone have a better multi-headed template, or at least a way to come up with a better CR gauge. I'm thinking +1 CR per head at least.

The hitdice add to the CR as normal. So it's +18 CR for that ogre.

The added hit dice improves the CR, base attack, skill points and even feats apropiate as monster race.
a giant seven headed has +18 CR, +4 attack, 4 feats and 1 skill point per die
Sorry if I mistakes I don't have any books here

Hit Dice are not added to CR in the same manner they are added to ECL. If you did increase the creature's CR due to the additional HD then you might want to follow the chart in the SRD and 3.5 MM. Giant HD are stated to be worth a +1 CR increase per 4 HD added.
