Polishing intake manifold

I would NOT recommend your FIRST polishing project be your intake. You may end up putting deep scratches in there that are hard to remove...PLUS, you will get frustrated REALLY quickly..

Also, if you have a chance to port it, go for it...DOnt worry that you have stock heads...You'll be ready to grow with it later..

I agree with this 100%. The first time I worked with gold was on a customers ring (making ring size smaller). Making the taper perfect & making the solder joint disappear was really tough. Once you cut too much material off, you are screwed.

But afterwards I worked with silver, and since it was cheap, I could screw up and not feel like I was an idiot.

Start with something that is flat, and big. Like a piece of metal in the shape of a 2x4 piece of wood. That way you can practice in one section, then move on. It's really easy to slip with a grinder. And if you do, it's really difficult and time consuming to fix. When you feel comfortable with it, try something with complex curves. This will prepare you for the intake manifold.

But don't let this intimidate you. This is just to prepare you. Do it yourself, and feel proud of it every time you open the hood of your car.
