I have a stock long block lq9. I got som3 l92 heads and had pat g spec me a cam. Now when he speced the cam I was going to mill my heads for a 65cc chamber and use a .054 head gasket. But I changed my plan a lil cuz I plan to spray a lil so I mill the heads only to 68cc and got a .040 head gasket.when I calulate the compression it remains the same. Will I need to have my cam spec changed?

 

No. You actually did the better thing by optimizing your quench distance with a thinner gasket. That will help with the efficiency of the burn.

 

Thanks
