I'm waiting to hear what head the OP's dealing with and what the goal of it all is. If this was some one-off, "uncommon task/head" I don't know why Dr J's would even be mentioned, in that they seem to be Chevy-centric, w/a little Ford and late Hemi thrown in for good measure. Judging by the OP's user title (Big cubic inches small Chevy!) and profile signature (Chevy man forever!), chances are fair to good that is a SBC deal of some sort.

Unless this is some sort of racing class that has limitations on what heads and intake can be used, or it's pro racing (to make money), or there are sponsers or money is no object, starting out by selecting the best head for the application from any good manufacturer will put you ahead of the game. The same money spent on better heads instead of porting stock or lesser aftermarket heads will be far more cost effective and will get to within a few percent of what a high dollar port job will get from a lesser head- and some heads will never measure up to an as-delivered aftermarket head regardless of how much time and money is lavished on it. And considering that even $2000 for porting/head work is dirt cheap (little more than a good valve job in some cases), it's easy to see how starting out w/a better head will be a better value- if money matters, that is.
