I think the first thing to go will be the pistons. Mark Levy's car blew the ring lands and he thinks it was due to overboost. You are correct that at some point the heads would need to be grooved and "O" ringed but before that the pistons and the compression ratio should be changed so as to use higher levels of boost. It probably also needs a different camshaft, vacuum advance and a lot of other mods so as to be able to tolerate and use the boost over 6 lbs. Besides if you are running an automatic the trans probably won't live long anyway over 6 lbs.
