The YB 0611 will be fine, but you 100% MUST let it rest when fitting it, fail,to do this is prepare to fail.
I use ARP stud/nut kit, torque in stages to 40, then 80 then 120lbft, leave a least 4 hours then go back and retorque straight at 120lbft.

A lot depends on what power you want to go to, if under 500, then group a by VICTOR REINZ will be fine, can get these from matt lewis, about Ł55.
You could use 6 long studs on a 200 block if you wanted, would need some machining for these to be put in, then 4 std stretch bolts on the outer end two holes each end of the head.
If using all stretch bolts then do as the book says, and do not retorque.
