New motor blowing oil on headers

how did you install the Balancer? with a installer tool or just try and use the crank bolt to install it? when i put the aftermarket brand dampener on my 440 i had to use a installer.
it made it so much easier to install. you can buy them or Rent one form the parts store. here is one that autozone has.
