Check out "loctite's flänstätning", somewhat thinner than your average silicone but it's always worked out great for me.
Of course "flänstätning" isn't a missguided attempt on English. It's Swedish, because a have i pretty strong guess that Malibu ss 64 is a Swede.
I think it might be called "Loctite Flange sealer/sealant" in English, at least that's the direct translation.
Or if you choose to go with just norman silicone there's a whole bunch of different brands that all work real good, just make sure that they withstand heat, oil, gasoline etc.
One of my favorite brands are Rhodoseal, thats also what we use at work when putting together oil pumps, gearboxes, engines etc...
Well good luck with the new engine now
Wow, hardly knew that there was so much to write about silicone....
I don't use siliacone on any oil pan surface. Because I've torn down so many engines when people use silicone, and the oil pump pickup is half clogged with silicone. So I use either #1 or#2 permatex on the gasket surface and use siliacone just to seal the mating gap on the outside where pan meet the block.
