I understand. I do plan on pulling the motor back out and just going through it again. I have to re-ring it anyways for boost. I know for sure my deck and head surfaces are flat. I had them take some off the deck when I first built it 6 years ago. If it's not worth the money and time to do the copper gasket then I won't. I like the Mahle gasket but I've been looking for other band and quite honestly, can't find anything but FelPro and Mahle.
