LA Pan with MAG gasket...NO WAY.

It's not the timing side he's talking about. It's the back, not shown in picture.
I know, I showed it because that is the only place you need to do anything, the back just fits in groove and the pan bolts down....maybe Magnums in Oregon are different but he 25-30 I installed are all working fine and leak free with all 3 styles of Kevko pans as well as some stock ones.
