Anyone done their own head porting?
Instead of sending it out?

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. As a member in here says. 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. Al |

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