Trying to build power....225 step by step help

So... valve change , major port work and different intake and headers + a bump with a shaved head or shaved block would help ? I would like my car to weight 2 500 pounds , and have a strong reliable 225 , dont want a 10 sec either , i just dont want to swap it for a v8 ( again ) ahahahah

Nothing wrong with that just as long your good with less 200 hp most likely unless you port out, even then you probably won't much more than around 225 hp.
