Resurrecting an old thread, but I think this is a great place to keep this information in one spot.
I'm undergoing this issue right now. I am using a Magnum Block, M302 Kevko Pan, and a LA Timing cover.
There seems to be 3 methods that I've been reading about:
1) Method One (Scram-Speed/Magnum Swap Method): Use the one-piece Magnum oil pan gasket, and cut off the front "U-shape" section. Use the LA U-shape gasket which has the "notches" that conform to the oil pan. This is the method that I started to embark on, being that it should be the "cleanest" method with only 2 seams being created, all visible, no glue involved. It would be nice if people can post pictures of how much you cut, where you put RTV to assure no leaks, etc. Pictures welcome!
2) Method Two: MagnumMopar's method, which is to use the Magnum Oil Pan Gasket, but to put two heavy globs of RTV where the front "notches" are.
3) Method Three: Cut out the wedges from the LA "U-shape" gasket, just enough to fill up the notches, glue/attach to pan, then use the one-piece magnum gasket.
Curious as of 2020, what is the preferred method? It seems to me that Scram Speed/Magnum Swap is the official "posted" method and it's the one that makes the most sense to me as you are not relying on heavy dosage of either glue or RTV, but I haven't seen detailed pictures/instructions. It seems like you have to cut really darn close to the bolt holes on the one-piece to assure no overlap. I've already cut off the front section (in a very conservative manner) and it seems like the next step is to cut more. So I thought i'd take a pause.
