The first thing to do on your next porting job is to use a new factory gasket as a template. Line up the gasket on the boltholes. Blue and Scribe the ports, or use a pointed sharpie.
I learned this the hard way: Tape-off the inlet edges because one tends to rest the rotating tool's shaft on these edges while grinding. This is especially true of the divisory wall edges. The grinding bit's spinning shaft resting on the divisory wall edges will tend to wear these edges down without your noticing.
Feathering out to the scribe line should be left for the very last stage of your porting job.

I dont believe salvage is recommended in this case. Great initiative, but look at the pic someone posted earlier.. you can see that you shimmed too much in the twin scroll portion on the inner wall. might not leak with gasket in place, but why use it if not necessary. You can find one for $30-$50. Start over and take the recommendations mentioned earlier
Nice work!

well thanx for all the comments guys BUT honestly the pic does not do as much justice because the part where it looks like there is a chunk taken off, IT'S not that bad honestly, and when i put the OEM gasket on (the metal one) the hot side set flash and after i installed it the other day i have not noticed any leak whatsoever and thats at stock boost since the car is not tuned yet....sooo will see how long this will last, ill update later on that.

Additional turbulence is one concreen , the other is if this part of the gasket breaks because it is not sealed. Not sealed means it is flapping and could break and go Directly into your turbo.
This was just learning experience. Remember to let the tools remove the material. Do not force them or apply tons of pressure. Take ur time. Its take the right touch that just takes time to get prefect. What tools are you using?
