Was just wondering if any other 10r owners have had their head milled. And how much was taken off. I am putting on the .45 head gasket but would like to take off more. The race manual tells you how to measure piston squish, but I don't need it to be the maximum that I can get. Was just looking to get about 1 more point bringing 12.7 up to 13.7. Any help would be great.
