i have an au spack falc and i want to get some head work done /porting .with out taking the car off the road cause i use it for work.
i can get a el head to get the work done to without taking my car off the road .
will an el head fit au 2?
will the rocker gear /cam from au 2 fit the el head ?
how much difference would there be between a port job on au and el (just rough estimate in kw)?
