LMAO please tell me your kidding...
polishing is just making it real smooth/shiny to smooth the air flow..Polising the stock size waste gate WILL NOT allievate boost creep..
the hole the exhaust gases are flowing through is the same size, there for creep will still occour if its gonna..
when you port you remove material allowing more exhaust gases to flow through the larger opening..then if your "polish" the hole u chamfer the edges and smooth out the holes intake and ex ..so this causes less turblance and increases flow slightly..there for reducing creep as much as possible
cast iron cant really be polished, if your doing it yourself with a carbide de-burring bit it will leave it smooth enough..and all edges will be rounded as opposed to if you get the hole drilled larger, then u have to chamfer all the edges

to port the wg youll need a carbide de-burring bit..they come in all shapes and sizes...avable from any GOOD hardware store/ machine schop..or a welding supply place will have them...
their abt 30$ a piece for the good ones...whatever u do dont try to use a dremel..youll go crazy trying..i used a air powered die-grinder and it took like 30 min to port it all nice...
there is no template..what u do is close the wg flapper then with a pencil trace arround it...then lift the flapper port to the line..but dont remove the line...you can check it as u go by closing the flapper...
way easy to do

I ported mine myself. It actually took me a long long time since i had never taken anything around the turbos off. I was extremely careful with everything I did. Took two weekends. To be fair, the first one was because a bolt froze on me and rounded off (and cracked my socket), so I spent many hours getting that thing off. Eventually just cold-welded a socket to the bolt and used a breaker bar. Worked nicely. Then it was easy to just pull everything apart and grind the hell out of the wastegate. Cost me ~$100 because I bought a grinder from sears. Electric Rotary Die Grinder and two deburring bits. I still get about a pound of creep, but that's nothing compared to the 7lbs i was creeping before!
