Please advise

First off, if I could buy a billet block for 8k, sign me up...

Second...Is it possible that the cast blocks are living on borrowed time at those levels, where the billet will add some insurance?

Third...Is it possible that the billet blocks are able to add strength in the bore areas, that will enable higher boost levels?

Fourth...Which can be repaired easier, a cast block or a billet block?
