I want to practice porting and polishing a little bit (on my old heads) and I´m thinking about using a DREMEL MultiPro 395PR tool. They are selling a nice set of equipment too. Is this a good choice? Anybody have a pics of their polished heads (except CLF)?

www.flat4.org is here!!! Sorry guys, in Czech only...

I have used one with out any problems.... for details check here: http://www.nateswaterart.com/vw/port_polish/

You can buy a mini die grinder at Home Depot for $25, and if you have a compressor you can do the porting and polishing that way. I use this one and it works great. I tried using dremel type tools, but nothing compares to a die grinder.


Standard Abrasives sells DIY porting and polishing kits that are great for VW heads.

In between the Dremel and the die grinder would probably be a 3/8" variable speed electric drill with carbide-tip cutting tools (www.mcmaster.com). Whatever you use, WEAR SAFETY GOGGLES!

are there any drawbacks to porting or polishing heads? sometimes i've read that they do not recommend one or both, is it just a money saving issue? i plan on building a turbod 1915 and i want to start practicing on my old heads before i cut up the new set

what bit numbers do you use?

They say you shouldnt polish heads on a carberated engine. The fuel wont tumble well enough with the air in a polished head. All I did on my heads were port the crap out of them. You should only polish on fuel injected engines..
