Not sure what the big round gasket is like nowadays (the one that goes between adaptor plate and engine block). But back in the '80's I was still using the Cannister and P-48 oil filter element and the gasket that came with the Purolator filter element was a thick pliable rubber.
For ease of installation, I used to dab my finger in a can of axle grease and smear the axle grease on one side of the gasket and stick the gasket in the engine block recess to make it stick there while I put the assembled cannister on. Pressing the cannister onto the gasket with my hand while using other hand to tighten the center tube bolt.
Used same procedure to install gasket under the adaptor plate when switched to spin-on filter. Never had a leak or mis-alignment for either intallation. But if your adaptor plate is too thin it could become distorted by tightening too much.
ALSO, need to take a look at the diameter of gasket on the spin-on filters, they are NOT all the same. The MOTORCRAFT FL-1A spin-on filter matches the adaptor plate surface the best.
