steady on dont get too excited that will be twice this year already

I have seen and used both ways, admittantly I have never gone over 600hp with a YB, and yes that had long studs (not specced by me) and yes it failed, i know several that have pulled the studs from the bottom of the block and just as many that have leaked oil/coolant and mixed, but I have also seen just as many std stud failures and cracked blocks that havent been modded to stop this happening.

So to me, and even my use I wouldnt long stud - my compressions for the rally motors are always over 9.1:1 and we have used them with and without restrictors on T34/compressor hybrids, so, I would say if you find a method that works for you just use it is my advice.
