i'd suggest that you only take as little as posible so that you can still get the diaper in and out. have you trial fit the headers yet?
man, that motor looks damn good sitting in there.
may i also suggest that you put tape over the intake ports. ya never know what could find their way into the motor. one time i found a valve body valve stuck in a port on top of the valve. it was after it hurt the motor though. lesson learned, got no idea how in got in there.
