I would look at the schematics of the K, and the F, on a site like
www.bikebandit.com. Check to see if they are the same, where the filter attaches, if they use the same filter housing, etc. I believe they do, but verify.
As to how do they compare with the OEM set-up? Well, they allow you to use an automotive spin-on filter -- much easier, and faster, to change the filter, less mess, too. No O-rings to change out on the housing, or the no-longer-used filter bolt. The spin-on filter has a built-in bypass valve, which is replaced every time the filter is changed (the OEM bypass valve is in the filter bolt -- heavy duty, likely will never fail, but...). You get a wide variety of filters to choose from, if it matters to you -- some filters have an anti-drain-back valve, if you choose to buy that type. If you want extra protection, you can buy a chrome filter cover, to dress it up a bit. A filter cover also protects the filter shell from rock impacts, though it is not necessary.
By the way, I put one on my '79 K, a few years ago. I had to cut off 1/4" of my Filter Boss, to make the adapter flush with the block, to seal. I used my moto-tool, with a cut-off wheel. Then I sanded it down, to get rid of filings and sharp areas; wash and dry before installation to get rid of any metal filings... I love my spin-on adapter. I have no regrets. Mine also has ports for an oil cooler, and an oil temperature/pressure gauge (I installed a temperature gauge sensor so I can keep an eye on the oil to see if I need to cover the cooler in colder temps.; I still use the OEM pressure/idiot sensor), so if it springs a leak, I'll get a warning when the pressure drops.
The difference in oil volume is virtually nothing. If you convert to a spin-on filter, fill it with the same amount of oil as before. If you install an oil cooler, fill it with the same amount of oil -- the increased circuit volume is so small, it won't affect the oil pressure enough to matter. Cheers!
