Looks like you weren't running enough boost.

what i think caused the damage was one lifter that actually broke where the roller pin goes through, basically stabbing the cam and setting it off compared to the other lifters then the lifter directly across from that one ended up seizing in the lifter bore which stopped the cam from spinning this way and sheared the cam bolts and all the rest was history. it was both the very front lifters. now i need to re-sleeve the one lifter bore because of this.

Also i only had one motor in before this one, which was just the stock iron block.

and i wasn't making enough boost only 14 lbs so that might have been the problem

Also this is just what i think caused it, and i feel its pretty accurate from how everything broke. and how things were sitting. but it definitely could be wrong.
