B55 is your man, he has the exact same kit.
I got the 6.1 on mine but thats purely because it left the door open for other engine modifications i had carried out whereas the B55 is essentially redundant if you where to get a S/C installed down the line for instance.
If you plan on leaving the engine alone after this then B55 all the way
