I am sure there has been,
Then that person usually goes out and buys a new set of heads and have them done professionally by someone who know what their doing.

If it was easy, then the girls would do it.

If it was easy, my mom would do it. (at least that's what I always say)
Yeah, I've done some at home porting, as well as valve grinding with Neway cutters. It's not a difficult thing, but it's one of those things that if you want pro results you should pay a pro to do it. My home porting efforts were on the mild end of the spectrum. Cleaning up the ports, a little blending, polish the combusion chamber and exhaust port. It was basically something I wanted to learn, but it was probably more of a vanity project than an actual performance boost.
On the other hand, I could probably make a few bucks on the side doing valve jobs, if I wanted to.

This website can give you some insight into the porting biz. The FAQs are good too.

I`m sure you can clean up some of the rough surfaces in the passages yourself with sandpaper, anything more than that i`d probably leave up to a pro. I`m sure its pretty easy to mess up a set of heads

Never seen home porting job end well unless somebody had prior experience and just did a light touch up job .

Used to do it when building in line 4 Suzi or Kawi motors, but sold it all when I got out of racing.
Not sure it'd be worth the time or expense now, considering the equipment needed and the time, it might just be easier to let someone with a cad/cam mill do it.
Seems I remember spending an easy 75-100 hours playing with a new head I hadn't seem trying to get the flow I wanted, lots of grinding, sanding and bondo trying to get the right flow.
Lot shorter time once the pattern was set, but still a lot of work, I'll let someone else do it now.
Especially if your only doing a motor or two.

Yup, unless they had several (as in many) sets of junk heads and a flow bench.

Yup and if you don't have access to a flow bench, step away from the die grinder.
