Dual or single oil filters ?

[FUNFER2]

With my new side oiler engine, I'm wondering if a dual oil filter is needed ?
I know that we want the best filtering for our expensive engines but, are two necessary if it's not a full out racing motor ?

I do plan on trying the "Filter Mag" that attaches to one filter. I like the clean appearance in the engine bay, and since it's so tight with a big block, I don't see a great location for all that's needed for the dual filters, bracket and lines.

I have a 8 qt. oil pan and if,.... I hook up and use my oil cooler, that may add two more qts. I'm installing my cooler mainly for looks, as I do not race a lot.

So, do we need two or not ?
