Trick flow heads: different installed valve height

It's a 1998 5.9 block from a Jeep Grand Cherokee. Now that my TF 190's are there, I'll check them out with my machine shop. They drooled on them yesterday. Thanks, rumblefish, for your cam recommendations. My machinist is smiling every time we talk. Working on a set of 1 7/8's TTI's. I'll send you pic's, if you'd like. Please keep me in the loop with you're'73, and your old Yeller. Paul.
