Gasket, although they're a pain to line up with the motor in the car!

Gasket !  put a thin dab of Permatex on the gasket  to stick it to the pump, then install.

I'm getting tired of all these experts telling us to eliminate gaskets or use silicone......Ma Mopar paid big bux to her engineers to figure out what would be best (cars leaking oil on the showroom floor would be a real sales leader!) and anyone doing a stock or near stock build should not follow race engine builders blindly.....those engines get torn down so often of course they don't want to use gaskets! I use gaskets and glue....no leakers here!

They have a term for this......"re-inventing the wheel".....

That little O ring only seals the shaft, but not the suction and pressure holes in the pump and block -- use the gasket and be worry free.

That one guy stating that he could not find the proper gasket is an interesting comment (in the link), but not uncommon.  I have found the same with AMC stuff.  I wanted a timing chain cover gasket only, but had to purchase an entire top-end set to get it.   When I put a new oil pump on my 440 it came with a new gasket.  I did not go and look for just that gasket, but I'd bet it's included in a top-end kit as well.

I googled high and low for that stupid gasket.  The only hit to come up was 440 Source.  I bought three of them.  You never know...........

I love these videos going around of these morons doing dyno pulls.  The swap out a chip and put on a fart can and do 3 straight pulls to a gazillion RPMs.  * POOF* one rice engine down the toilet....

It seems they don't know what the red line is for on their tachometer...maybe they think they're supposed to rev it all the way to the end?

Personally, I think the best value all around is the Melling high volume.  Feel free to argue with me. The Moroso pumps are relabeled Mellings.  If you do go with the Melling HV, get the bolt kit also as the stock bolts are too short.
