Are you willing to up your octane. 9.6 to 1 is already getting up there on iron heads. Aluminum heads would probably be a good investment if you are going to try and run boost.

He has aluminum heads already. You could run a blower, but with non-forged pistons and rods, you'd want to keep the boost low and run the highest octane in your area. An intercooler would be a must and water/meth injection recommended but not required. I'm guessing this is gonna be more of a street vehicle than something going to the track?

He is right on. Sorry I missed aluminum heads in your build list. Water/meth injection would be a lot cheaper then a intercooler set up for a roots style blower. Plus you would get the octane boost to help control detonation.
