Thanks for chiming in,Shawn! I'll run out to the pole barn in a few minutes and take some shots of ALL the cap mating surfaces. I can definately see evidence of "walking" on #2..#3..and #4 block/cap mating surfaces! So..you think just the stud kit alone will eliminate the "walking" issue? BTW...after talking to Randy Thursday...I will be going with Shawn at St. Clair Engine, to be doing my machine work!..he seems to be Mopar-Connected,for sure!
