nah standard plugs are easier to tune...
Another cost you may not have considered yet; Do you have a bunch of standard plugs still? If you switch to turbo you're going to have to buy plugs too and those little guys get pricey.
Turbo heads do make some more power, and burn fuel my efficiently but if you're very used to your standard button AND have a bunch of standard plugs still, I wouldnt make the switch personally.
