But here's my 2-cents worth. He should Send them to Brian @ IMM or Dr. J's and tell them what he wants from them and they will get him what he needs.

I personally like Dr J's phylosohy on the subject: (copied form their website) At Dr J's Performance we do not believe on individual stages of porting, because it does not benefit the costumer. Our goal is to provide the customer with most amount of performance per dollar spent. Every head that leaves Dr J's performance is ported to its maximum potential.
