It looks like my biggest gains will be found through the headwork and a new cam. This is good news as I'm trying to keep this cheap. I think I have sold myself on a basic rebuild and any minimal required machinework, along with the afforementioned mods. This will give me a fresh motor with a little more power and hopefully not be too expensive... I have an Lsx project around the corner, and we all know how expensive those are.

I see some basic rebuild kits on ebay around 400-450$. Im sure the cam is OEM spec and useless to me, and I have no idea on whether the other parts are reputable...However, they do say they can build a kit for you. Any experience here? Would be far easier to just get a kit and go. Is there a final answer in who puts together the most cost effective rebuild kits or am I on my own?
