getting a cometic gasket for my z6 but what is the standard bore? as the gasket ive seen has a thickness of 0.030 inch with an 76mm bore

Would it fit?

 

stock bore is 75mm and stock mls headgasket compressed thickness is .037"

why are you going to get a cometic??

 

getting one as ive seen one for sale with a arp head bolts

so the cometic gasket wont fit as its 76mm bore yeah?

 

i ran a 76mm Cometic on my stock bore a6 and it worked just fine. never once had an issue

12psi on a t3 .42/.48

 

 

I know this is an old thread but I was wondering if anyone knew if I could use a 79mm head gasket on a stock bore without an issue

 

 

Not sure what that means but was ordering a gasket and it says for d16 but bore is 78 or 79 mm

 

if you havent ordered one yet find a place that has the correct one. Majestic honda is a good start. If you need a gasket for boost oem MLS is perfect.

 

First off, don't bump ancient threads. No one likes it when people do that.

Second off, 79mm? Are you ******* high? If you're rebuilding and had your block honed, you should use 75.5, maybe 76. If you didn't, and you're just replacing it, you should use 75. 79...that won't seal for ****.

 

well said
