This would be just for some basic head port matching. What works best? Those sandpaper rolls on a dremel or something that cuts harder?

Interested as well. I know Tony uses carbide, but no idea what bits.

Sandpaper rolls seemed to melt the plastic rather than grind it out, in my experience.

I used the stone bits that come in the Dremel kits.

I have some stone bits. Do they tend to clog up and get coated with plastic or do they stay fairly clean?

I'm not sure if I have the experience like Tony to use carbide bits. I'm sure those would chew through plastic fairly quickly for a first time porter like myself. I wanted a bit that I could work with nice and slow while taking my time.

I might be better off just sending it to Tony and have him do it.

They did not clog up as all. It was my first time porting an intake too and they worked well for a beginner.

Sounds good. Thanks for the info! I'll give those stone bits a try.

get small diameter bits to deal with the corners.

Bump, Bramlok, did you do this? How did the dremel/stone bits work out? Any before/after pics?

I used sandpaper rolls for the Dremel at a somewhat low-medium speed. No melting or clogging and worked great.

Sanding rolls work great, you just have to start at a slow speed then work it up.

i agree

That's what I did, the material of the Fast came off in shard like pieces rather than fine dust or melted ***** from what I remember. It was insanely easy to work with.

I used a combination of both the stone bits and sanding rolls. Kept it at low and medium speeds. It turned out pretty nice. I port matched it to the heads and smoothed down all the rough surfaces. It took me about a weeks time working on it a little bit everyday. In that week I spent maybe 7-8 total hours but went really slow and took my time. Sorry I didn't take any pics mostly because it was such a mess when I started the grinding with plastic shavings everywhere.

How far are you guys going up into the runners and how much material are you removing.

I'd say carbide, just keep the speed down. Finish with sand rolls on a die grinder; also keeping the speeds down. Helps to limit them by limiting the air coming into the tool.

Bump for anyone that took pics while doing this.
