Bunch of good insight thanks guys. So what I've gathered is its possible to gain a little performance depending on your ability and knowledge of how to make these different modifications work together. So I still have a lot learning to do.
So I think I will just keep this first engine stock for now until I have a better understanding of what I'm doing. Since this is my first project and I'm a noob, just taking this apart and maybe getting a manual to reassemble will be a good learning experience. I'm also in school so I'm hoping once I take my engines class I'll have a better understanding of what I can do. Until then its just research, research and more research.
Wallet isn't that thick so I think these responses have changed my mind to hold off and learn for myself. Thanks a lot guys ya'll have been a really big help.
