the internals isnt' the qeustion in your case. and there is no predefined boost level where your engine will blow up, many different variable.
your headgasket is going to blow before anything, and with higher boost, it's likely that you could lift your head.
get yourself a metal headgasket (apexi, greddy, i would say cometic but a few others have bad expriences on here, i personally have apexi) and arp head studs. it will be a cheaper investment, beacuse if you do blow your gasket or lift your head, you could possibly damage other things.
the metal HG and head studs will give you peace of mind
