The ones I pulled are between 51 and 53 thick now. I want to raise the compression not lower it. I only had a problem with the 1000$+ for the multilayer gasket, the 240$ wasn't a problem just always thought copper was more suited for high compression race when you are pulling the engine apart all the time. Plus I wasn't keen on doing the ring job to make them seal better around the cylinders. I have no problems with the asbestos clad gasket. The one engine i pulled apart had over 150,000 on it and it was in good condition.
