4.0L HO Jeep Engine Build

Hi ramcharger. I just joined the forum. I wanted to ask you a few questions. I have a jeep just like yours and would like to rebuild it as well. The difference is I would like to turn it in to more of a performance machine. I have read your entire thread so far and find it very interesting.
Are the stroker kits the only way to get major performance out of this engine, or could I have the cylinders bored over and put in new forged pistons. I am not oppossed to supercharging the motor down the road, but not until I have completely "built" the motor.
I am a noob to building an engine but I have replaced engines in two different vehicles though. Any opinions would be greatly appreciated. I currently live in South Florida so I doubt I will have a problem finding someone to do the machine work on the motor.
