Help on doing it your self (Porting & Polishing)
 

I have a used set of Holley systemax heads & I was wanting too do some porting on them. Where can I get some bits too do the work? I know summit has a set of porting & polishing tools but I’m not sure it they are the right thing too use on aluminum. Also are there any web sites out there I can learn more? Make me an offer on the heads if interested. They are like new. Also have a Holley cam too.
