How much of a bump are you trying to get? Mr. Dos Equis...stay thirsty my Friends

 

Just trying to get whatever i can without milling & more $,i know the .040 will get me 11.1 wich is good for me just wanted to know if they had them in 4.065 bore.

 

Not sure,its a brand new ls3.i heard the stock ls3 sits .006 out.

 

You don't want them exactly the same size as the bore. OEM gaskets are 4.080 bore anyway, so the Cometics being 4.085 is going to be fine.

 

I ordered them.
