Beehives are for bypass oiling. You need to run the spin-on relocation type kits with the 1/2" NPT size fittings.
As for the header issue, you should be able to get some pipe nipples, elbows,etc... at the hardware store that would be long enough to get you past the header tube, then connect your flexible lines.
running the lines through the inner fender, and mounting the filter on the side of the frame might work also, that way you reduce the oil pressure lag time. Just a suggestion... and make sure it clears the tire when turning!
With that camshaft, I have to ask what are you using for rearend gears?
