Default New Head - Will It Need Re-Mapping?

Just I'm getting a new head on my 3 door as the old one is just a paper weight now.

Will it need remapping as the CR will have changed?

Cheers.

If the amount of air the head flows has changed at all then yes....

No, its a standard head again, but the old one was skimmed to death, new one is not even skimmed so CR will be lower. Not by a lot, but I don't want to take any chances.
