How many people do you need to be able to make this happen?

You may be able to get away with 91. The trick is to keep the cylinder head temp down to help prevent detonation. In the summer you may need 100OC UL Pump or equivalent. The higher duration cams wont require any higher OC then the stock cams, actually they would help prevent detonation. The higher overlap will bleed off cylinder pressure at lower RPM's. Its the hight comp pistons that will cause the engine to require a higher OC.
