hd-dude is a pro so it's good you've gotten his attention.
Me, I'd say that Woods cams are certainly good, as are numerous others. There are a whole bunch of Evo cams out there so decide what you've got in mind for your motor as a final product, what your riding style is, and shop for a cam that fits both. I put SE heads on mine and a Andrews EV27 cam along with SE ignition and have been happy. I'm not claiming that's the perfect combination, just that it suits me.
About carburetors, I just re-jetted my stock CV and it works fine. I know that some swear that Miikuni carbs are a must but the tech doing my work talked me out of buying one saying that I'd probably never appreciate the small difference. I've heard that the CV carbs will be OK up to about 100HP so if you're really looking for 90HP in the end, you may find a Mikuni justifiable.
