I have a 94 honda accord LX single over head cam with about 130 hp. I need more power. I am pretty new to all this. my friend said to get a new engine. I saw that I could fit a h22 in the car or I could put new h22 heads on my engine. I am think about going with the heads. Should I? What else do I have to replace. And in either case what web site is the best to find parts.
