1.6 head = no.
1.5 SOHC was more mitz based than the 1.6. The 1.6 is like a mini version of the hyundai designed 2.0.
WRX or EVO off the line?... maybe if they are looking the other way.
If your going to try and make the 1.5 gofast, go boost. That motor seems to handle pressure just fine. 310 degree cams.... not a good idea. Your head design as it is right now doesn't flow that well at higher rpm. That and good luck idling. Stick with stock cam, install a turbo (scoupe manifold will work), spend some money on a good fuel system, and the other goodies that go along with boosting. You will be much happier than if you try to go N/a with it.
