That's actually how they're supposed to look...I saw the same wavey piece on mine and wondered about it. It is how they are designed. They should not be over torqued to the point that ring is flush. Check with the A & P's on here or locally for the correct torque on those bolts, but be wary of just looking at something, presuming it's not right and then tightening fasteners without knowing the proper torque. You're right to ask first
One other tiny observation...I would suggest plugging any holes or openings into your engine so dust, debris, bugs and metal shavings don't migrate into it. It's stunning how much stuff flys around in the air during a build
All best and enjoy your new engine...it's a big moment in the build
