Kohle started his career in Cosworth's F1 program, so he'll build the heads..if you want, with stud mounted roller rockers, they'll be good for 100,000 miles w/o anther issue. He'll use F1 technology in the valve guide technology he'll use. Their Stage 3/4 package is good for 630 to 650 RWHP; but our 3.90:1 rear ends will make it feel like a 100 hp more.
