Not sure about that, on a SS or Comp Combo @ 390 on the seat and @ almost a 1000 over the nose it is a struggle to pull the motor over by hand especially with the plugs in. we always bump it with the starter when checking valves. As far as a bolt goes use a ARP bolt, should good to go.

the ARP 134-2503 is specifically made for turning the engine.
with all the rockers on and adjusted should be fine.
Rockers on one cylinder, probably not a good ideal
