I have the RA manifolds on my '64. If the motor is still in the car you will have to remove the motor mount bolts one at a time and jack the motor up one side at a time. The passenger's side is cake but on the driver's side you will have to remove the Z bar and disconnect the steering shaft from the coupler and pull it up through the interior enough to get it out of the way. I just went through this when I swapped my heads out.
