What gasket to use after porting o2 housing?

[Red97Eclipseboy]

Hey guys. A buddy of mine is porting my o2 housing this weekend, and I was wondering what happens with the gasket. Do we port to match it... or is there another one to buy? I looked on vfaq.com and I found some info; however, anyones' advice would be awesome! Any info from anyone with experience from porting their own o2 housing would be great. We're a little weary of this, so we just want to make sure we know what we are doing. BTW, he can port with the best of 'em, he just want to make sure he doesn't mess this up. He got game! Lol! He just doesn't have much 'DSM' experience. Thanks!

which gasket are you talking about?

You throw away the old gasket and you get a stock SS gasket which is thicker and stronger than the paper stock gasket. When you port the O2 housing, the openings get ported to match the gasket. What really gets ported is the inside of the O2housing. This is mostly how you're increasing the exhaust flow.

Oh, and you can get these SS gaskets from either Road Race Engineering, DSMotorsport, or anywhere else.
