Oh, don't forget to drill & tap the center stud location to accept the longer studs like in the #2 & #4 shaft hold-down positions. There have been a number of center pedestal cracking reports on here, and I wouldn't run a Victor head w/o this mod now.
I didn't drill the center deeper, but it has the additional support screws in the three center stands, so it is very rigid. I know the center stand is thin, but I have to wonder if the cracking issue isn't from valvetrain instability. After all, it breaks enough other parts.
