Oh man that sucks. Sorry to hear that.
I am praying that all goes well with mine when it I get it back running.

I will check but if they gave you the MS4 then that is your problem. The MS4 has to have the heads flycut I am pretty sure.Do you remember the exact specs on your MS3? Mine vary a slight bit from what is posted on the web site. Hell the specs off the cam card are bigger than the MS4 according to the website as well my card said 238/242 and .605/.612 lift. Smaller than the MS4 on the intake side but more lift.
Even though I don't think it hit all the time the indentations on the pistons are more than just a slight tap theres 1/16th in indention, and the valve face smacked it covering 40% of the valve diameter came in contact. At first sight I actually though it was valve reliefs until I saw the jagged edge and remembered LS1's don't have this.If it was just the smallest amount of contact it hardly could have been noticeable from those tests, but would break a valve over time as what happened.
Gotta check when I get home stock length I think. Like 7.4 or whatever comes with it.What was the pushrod length?
holy cow, thats a freaking insane liftMS3 are 237/242, .603"/.609", 113 LSA
I think they may have just cost you your engine.
His cam card said his had even more lift:holy cow, thats a freaking insane lift
