Yea, I recomend you get a wilk chip and when the MAF kit comes out get it. For A header get a B&B or SFR Both are very high quality. Lightweight pullies are good, they will help the engine spin a little faster and free up maybe 2-3hp. Spark plugs arent gonna get you any more HP, I would stick with a good set of copper plugs and gap them correctly. As for ignition Just check out the MSD web site. There is a ton that you can use it all depends on what your looking to do. Also a ignition system would give you much HP but it will make the throttle response better, If your looking to make alot of HP eather your gonna have to pop that engine open and do some big work or your gonna have to go with a supercharger or nitrous. Other then that all those small mads will make a small difference and change the attitude of the car
