Milodon op gasket
I have a one piece. Works great on my Milodon roadrace pan. A smidgeon of RTV on the corners,as usual,is all I did.My gasket had torque-limiter inserts.I think its on its 3rd life. The last install was about 10 years ago.
If you use the RightStuff,it will make that reuseable gasket, a 1-time gasket. That goop is almost impossible to get off the gasket without cutting it up. But it will really,really,really seal.
