I'm in the proccess of rebuilding my 95 gt engine on a college student budget. I don't really want to go crazy with it just some simple cheap upgrades like e303 cam, 1.6 roller rockers, comp cam valve springs and pushrods. Here's my Delimma, I was gonna port my stock heads but while looking on Craigslist I came across a guy with some gt40 heads for $350.00. How much more power would the gt40's make over a ported stock set?? Oh ya and one other thing if I got the gt40 heads would they still work with the stock gt intake or would I have to get the cobra intake? And lastly will the stock injectors work ok with this set up or should I upgrade? Any suggestions would be greatly appreciated! I'm kinda a newb at all this haha!
