Gasket for ported 2g manifold??

[Infamous33]

Maybe I haven't looked hard enough or my math skills aren't what they used to be but I have a ported 2g exhaust mani that I purchased and the outlet is ported bigger than stock.
I know everyone says the 7 cm gasket, but measuring it, I only get about 58ish mm. Is the 7 cm the only choice over stock size? I plan on porting the turbo inlet to match, but that is sort of tough without a gasket to go by.. and I want to make sure of what gasket I will use before I start cutting.
Not sure where to get one, so if anyone could also point me in the right direction with that as well, thanks !!
FFWD shows an inlet gasket, but doesn't list the port size....

I have the 7 cm gasket..works just fine..If you need more room just cut into the metal 7cm gasket..

the gasket should match the head anyways, you should port the manifold to match the head no?

He's obviously referring to the collector side of the manifold...

I think he's talking about the manifold outlet, into to turbine housing...

Collector, that's the word I was looking for..

OP - This mentions which one to stay away from and which one is the good one: http://www.dsmtuners.com/forums/art...tainless-steel-7cm-turbo-manifold-gasket.html

I have a gasket that's just like that..Don't know If it's from same vendor or not..Never had a problem..Not to say that I won't tho either..

Well I just noticed that ffwd lists their gasket as 61mm hole, but I noticed no one mentioned the copper gasket option yet.
SEC lists what I believe to be the same copper gasket (as it seems they make most of the gaskets for ffwd..) however it doesn't list what the hole size is. I was going to call them in the morning to find out..
Is copper not the best choice, or waaay down on the list?
P.S. it is $17 at ffwd and like $12 at sec

The term "7cm" is not referring to the inlet of the housing being 70mm....it means the gasket is larger and fits the inlet spec of the 7cm2 turbine housing used on 16G-20G turbos.

Although Ive heard mixed thoughts on the use of Copper gaskets, I still would go with the OEM 7cm gasket! I Can't seem to find where I purchased mine, but dont be fooled by the ones selling the Thick Stainless steel gaskets as they are know to crack and fall apart! As 99gst_racer has showed in his thread.

Edit:

Here I found it at Machv.com, Not were I got mine but this is what it looks like! Also, I know you can find it way cheaper than what they have it listed for!

OK found some VERY similar on ebay:

Also I would stay away from These as they are usually found next to nothing (most of the time), but i've had a few and they ALWAYS burn up and blow through!

Hope all this craziness i've posted helps!
