I was looking at the website for Tudor's performance and I noticed that they sell "No Blow" base gaskets.

What's different about these gaskets than normal ones?

If they are different like a copper head gasket is different from a conventional one, I would like to find a place that might have one for my RM.

Any help appreciated

 

found something similar from Cometic gaskets.
