Blew the HG... Again!

Ok, just got the turbo on, was going to go do some tuning on the AFC since it was warm out. Yes the truck was at operating temp before laying on the boost. Made 49 psi on a few passes and the last one ended in a pop followed by steam. Thought maybe that I blew the frost plug on the back of the block, nope. The HG was sticking out of the back above the frost plug. The head is studded and o-ringed, retorqued every other oil change. Dont understand why it popped again? I thought I could hold more boost than that. I just put in a .020 Marine HG in April. Now I gots a few questions:

Do I need to have the o-rings redone?
Anything to do to prevent this from happening again?
Thanks in advance.
