If your not going to degree the cams and have an extra set of hands to move the chain guides when going back together , then just inframe . The outer two head bolts on the exhaust side will not come out . They should be vice gripped to hold them up enough to clear the block when removing and installing the head .(speedpimp @ Feb. 12 2007,22:11) Has anyone removed a busa head without taking the motor out or is it even possible. I plan on doing a little head work and am trying to determine whether to pull motor or to just pull head out. Which way should I go...any recommendations?
