Mac Header Install Tips

I am going to be installing the mac headers on my z-28 is their anyone out their with tips on how to make my install alot easier. All comments are welcome

I just installed the headers and y pipe. before you even touch the headers take out the spark plugs and take off the wires. You may have to use a crow bar to torque the engine this way or that to get them to fit, i had too. they are a nice addition though
