You need to decide how much power you want to make. You can do it with either heads/cam or supercharger or turbo. If you do heads/cam and a supercharger or turbo, you're gonna blow up the engine and break your trans or rear. Pick a horsepower range and then decide how to get there. You can bolt on a supercharger and get in the 425-450 hp range. You can do the same range with just a cam. When you go over 500 hp you're gonna start breaking parts and will have a real tough time staying "legal". You don't need to pass the emission's sniffer test with a 96, you only need to pass the computer plug in test. You can put in any cats you want and it will look legal 99% of the time and with rear O2 sims the computer will pass inspection. IF you get too radical of a cam, the computer might not be able to deal with the cam or crank sensor and throw a code which won't pass. I think you can reach the power level you want with just a cam swap but since you're that far apart doing heads is a good idea. Start with the heads/cam and then worry about a supercharger or turbo after you rebuild the short block with better pistons and lower the compression a little.
