How hard is it to port, polish, match and face heads yourself?
Unless you got the right gear and know what your doing there's a lot of chance for things to go wrong. Not saying someone couldn't do it successfuly but id rather pay someone to do it.

If i were to do that to the super6 heads, this will give me more mid range to top power than low down,
Is this right?
I did my heads using a Standard Abrasives porting kit, a Super Shit die grinder and many many hours. You also pretty much need to get your valve seats re-cut afterwards to be safe.
Get some sand, take off everything attached to the throttle body so you can get unrestricted access to it, start the engne, rev to 6000rpm and feed the sand into the WOT....
Seriously, as already said unless you have the correct tools have practiced hand porting heads... it's going to be difficult and possibly stuff the heads up. Also head work should be in conjuction to other mods like a CAM and the head work should match which does take a bit of knowledge.
There are plenty of article on the web(Google is your friend) and if your really stuck on doing it yourself get yourself a pair of second hand heads from a wrecker and go nuts.... this way of you stuff them up you can always put your orinigal back on.
Unless you have a fair idea of what your doing a home port job is really just a good clean up with emphasis in minimal metal removal. For a stock cam'd engine you want to maintain a small port/runner to keep the airspeed up. if you hog out the port in one particular are it will loose a lot of airspeed causing all sorts of issues i.e. a loss of torque. Big ports/large cross section runners are only good for engines with big cams and lots of revs where low rpm performance and throttle response isn't required.
There are certainly gains to be had on a stockish type engine with pocket ported heads/cleaned up runners.

Its def a big job to do it properly. I did stacks of research on what to shape and where before i did mine, then had them faced etc and flow benched to double check how close they were.
I spent a lot of time doing it, and thats using all the proper tooling. Was a great experience though, and I got some fantastic gains on a cammed engine
