General Discussion / Hydros again

I just got this 2003 Stone for $500. It's got Mistral exhaust, Ikons, dual discs, Cartridge emulators and an LED headlight. And... a ticking left side top end.
I'm not worried since the parts are worth so much more than I paid. No idea of mileage since the speedo has been replaced with a nice aftermarket. It looks well kept and low mileage. No history because the previous owner bought it at auction, not running. Soon as he started it up, discovered the noise, did some research and put it up for sale. He got one offer of $500 but didn't accept it because the guy intended to part it out. He wanted to see it repaired. I told him I intended to fix it, so he sold it to me.
I pulled the valve covers and it's got the original, from the factory, smooth lifter adjusters. Should have taken a photo, but think the spring retainers are dark. I'll drain the oil and see what comes out. If all clean, pull the pan, and if nothing, pull the front cover for a look at the pump.
At first I was thinking that a lifter just hadn't pumped up yet from sitting a long time, but now I'm betting this is the reason it went to auction.
Since the hydro kits are crazy expensive, what are my options? If the cam looks good - can I replace the lifters and pushrods and be done with it? I have another engine and could do a swap. I haven't looked at the clutch yet, but if the engine recall hasn't been done, I wouldn't expect the clutch to have been touched either. Haven't checked out the triples either.
It's a pretty nice bike with no rust, and I've got enough parts to make it right. So I won't be parting it out. I'm just trying to figure out which direction to go with it. Since I prefer carbs over FI, I might make that part of the project. If anyone knows the ins and outs of that conversion I'd like to hear what's needed. Will PHMs mount right up?
From what I've read, the hydro is a great engine, with the normal solid lifter valve springs being the root cause of all the trouble. If everything looks good with little to no wear, can the valve springs be replaced with lighter ones and all will be good?
