Maybe not gasket after all. Measuring cover and depth in case.Cover is .010 deeper step than case. If running gasket it will dang sure have crush.only way to hold gasket will be small dab sealer or just set in place and then bolt cover on.

Cover will not seat with gasket,so guessing machined to seal w/o.

Greg said they see yoke push out on dyno,so guess getting excited over nothing. Well except the big cost piece of build.Engine don't count already had those.Ask my wife see has been told that lots.LOL
