The problem is going to be piston to valve clearance with the Magic Stick camshafts and those heads. Before I'd attempt that one, you'd definitely need to measure your free valve drop (distance the valve travels from the seat until it hits the piston at TDC) for intake and exhaust. That'll tell us quickly if you've got enough room for a Magic Stick! My gut says you'll probably need less duration!
