I forgot this part; without me even mentioning the stud issue, he said they automatically replace studs as needed.

$800 sounds reasonable.
Full gasket kit (both jugs) is a given.
Has your inner cam bearing been upgraded? If not, this is a perfect opportunity.
At 36k miles, you're due for lifters.
If you ever wanted a cam upgrade, now's the time.
The gasket kit will come with new valve seals. I'd make sure they intend to put them in. Odds are your valves, seats, and guides are fine, but I'd make sure your guys give them a once-over.
When it's all said and done, you'll end up with a better-than-stock motor that should give years of trouble-free service.

I hadn't thought about the cam, either, so now I'm going, "Hmm..."

Me personally
.if my bike wasnt smoking or using any oil
..and I was on a budget. I would just remove the problem head to replace the stud and replace the base gasket. With your mileage, Id replace the lifters as well
.but not cheap no names.
With $800, a top end freshening is vague. I suspect new rings and all new gaskets. If thats the case .seems high to me. Id verify what exactly youre getting. You may not need all those services at this point.
As others have stated .this is a good time for cam change and cam bearing change .but not required.
It all depends how much you want to spend and how quickly you want to get back on the road.

Well, she's in the shop. All gaskets to be replaced from the base gaskets up, including the pushrod bases. Also getting the 3-hole fluid change.
And, I asked about an Andrews EV13. He's going to check crank runout and some other things and give me a call.

The following post will show my mechanical ignorance, but I wanted to update everyone.
The shop guy called today. He gave me an update on what's needed and I agreed to it. Get this: he said I have aftermarket pushrods. I would have never guessed. He also said that the only reason he could imagine for this is that it also has an aftermarket cam. He'll know more once he gets in there. So who knows? I might have an Andrews already.
The bike was sold to me as bone stock, and I now know otherwise. When I jetted the carb two years ago, the first thing I noticed was that the protective "bubble" or whatnot covering the mixture screw had been broken, plus it had the aftermarket high-flow pipes. So it sounds like someone might have installed a cam and the pipes, then tried to adjust the carb to accommodate without jetting it.
So between the pipes, the jetting two years ago, and the K&N air filter, I guess I have something of a Stage One kit, in a manner of speaking.

Your getting great advice. Interested in finding out what cam you have.
Even if the cam bearing has been replaced and is the improved full compliment Koyo/Torrington B-138, it's cheap enough to replace while in there. That's the only bearing to use, the stock Ina bearing is a lower quality design and it can be an expensive ordeal if it fails.
Same with lifters, replace them.
As mentioned, the Cometic SLS (single layer steel) for base gasket, and MLS (multi layer steel) for head gasket are the ones to go with (have your shop purchase the cometic top end gasket kit). Having the cylinder bases machined flat is cheap and easy while it is apart. The factory never did this when manufacturing, and was one of the contributing factors to the problematic base gasket leaks (along with poor quality base gaskets and owners not letting cylinders warm up prior to loading the engine).
Keep us posted.
