Cruising below 2k in 5th gear. I heard a small noise, the engine speed went nearly to redline and a lot of smoke bellowed out the back. Shop said the heads were over-ported and the deck was too thin to support the pressure. A chunk broke off and sent crap into the motor. My entire motor was toast.
7.4" pushrods, no milling. It came as a package from TSP with the cam, so you would assume they were correct. Unfortunately, I had bought the kit the year before I installed it but I hurt my shoulder and it sat on the shelf until I could install it the following year. TSP told me to take a hike when I told them since I had ordered it a year prior, even though the heads had about 3k miles on it.
Lesson learned.
Edit: FYI, this was back in 2008
