Sorry Greg . not knocking your product just curious to if any one else with the issue as i thought it might be common with the gasket as stiff as it is. Using your gaskets in the rest of the build as well. Great product. Thanks to your rear main seal and Monty Smith advising me to clock that seal 12 and 6 oklock. No leaks there or any where else. Havent measured everything yet but will in a few. I just think a soft gasket might seal these covers. if i could afford $600 covers i would of bought them.
