send it somewhere with a guud reputation like portflow if you're insistant on getting headwork done. I hope you've got your bottom end done already, if not, spend your money building your block first.
Not entirely true. You can open up the passages, and flow bench it, and actually LOSE flow. You cant expect to just open the ports and make power. Manufacturers put bends and bumps in their ports for a reason. You have to know what your doing to do it right.
