Sounds like you should look at a package such as the Edelbrock performer RPM. This is a matched package of performance parts that are designed to complement each other. (Cam, Intake, Carb, and heads.)Drift said:
In terms of rods the stock parts should be fine, but with pistons/rings you will want forged or hyper flat tops to raise you compression. Use quality bolts such as ARP, and have the whole assembly well balanced.
This will give you good reliable power, probably about 250-270 rwhp.
Most importantly, find an engine builder who you are comfortable with, and talk through the whole project, making sure they understand what you want to achieve.
Good luck
