LA Pan with MAG gasket...NO WAY.

Did you look at the pics? Its not the issue magnumswap was talking about. its the REAR my pan, and another guy that posted a pic, the pan has a lip coming up...

I did look at the pictures. Did you read my post?

The thing I don't understand about all of this is that there is no difference between an LA gasket and a Magnum gasket around the rear main cap, other than being one piece on the Magnum gasket. In both cases, the gasket is intended to be captured by the slot in the cap, and the ridge in the pan squeezes it.....

My reference to what MagnumMopar posted was to add another voice to the fact that the gasket DOES work, on BOTH ends, if you are aware of and deal with the gaps created by the magnum gasket.

Maybe you haven't ever built a 360 before? If you are used to a 318/340 pan, I can see your confusion, but I think I spelled it out pretty clearly already how the gasket is intended to work, and there are thousands of them on the road with that gasket that didn't have to have the pan smashed flat.
