"J" heads porting?

A while back I posted a thread regarding my mildly ported and cc'd 1.88 "J" heads. A few of you responded with some links to some head porting guys...supposedly the best in the business....and I can't find the posts or the links. Could any of you possibly re-post the links and contacts? I'm getting ready to do the heads now, and would like to talk to the experts regarding these heads. Thanks!
