I could only find 6 bolts that hold my 86 SPFI EA82 camcase to the head. It's still stuck on. Before I really get violent with it and bust something are there really only 6 bolts?

Found the other two bolts. Before I replace the cam case, missing lifter and rocker, What would cause a lifter to go through the valve cover? I just don't want it happening again with the new cam case and lifters.

I've got 8 bolts holding the cam carrier to the head on my carb'd ea-82. 4 on the bottom and 4 on the top, both on the inside and outside of the cam carrier.
