I broke the stands off on cyl 3 on my 4.0 jeep. Jesel set up using 1.7 rockers. Retaping the holes to 7/16ths made for a thin side of the rocker stand. That coupled with increased r's and a super agressive ramp on the cam did it in. I took a bridgeport to the top of the head and mounted a 1 1/4" steel bar and relocated all Jesel rocker stands, works like a charm.
