2004 S - Has anyone installed new exhaust manifold gaskets lately, porsche part #996 111 107 55. The bolt holes line up but the oval exhaust holes are bigger on the new gasket leaving not much coverage at the exhaust holes on the heads. They barely cover the curved channel just above the exhaust holes on the heads.
The original gasket hole size were (50.8 x 33), the new are (60.3 x 39.7). I checked the Porsche part # for the 996 and it is the same part. I spoke to a Porsche dealership and they said it will work. Does anybody have experience with the new gasket? I'm tempted to use my old one with some permetex exhaust silicon.
What is the purpose for the curved channel above the exhaust holes on the engine head?
