Ive never had anything ported for me, so Im not sure if all machine shops can do the work or not. If you just want to smooth out the roughness of the insides of the intake runners, you can just use a die grinder and some sanding bits. I posted a thread asking about this about a month ago. A few people have me some real good info, and explained to do it yourself. You might wanna search for it. - John
