back up a minute! did you replace the original petcock with Raptor yet?

a workaround, is to turn the original petcock to PRIme.

if petcock is your problems, then it is a little unusual for it to present itself as just reducing power. Also it tends to happen sooner than 28K miles.
Mine would silently die completely at highway speed, at 7-8 years old, at about 3000 miles.

let us know.

I use gasoline.
Whatever, you know it's leaking.
I know what the costs are for failing to get it right.
It's expensive and a hassle to get in there.
I let experienced professionals decide.
A machine shop or a mechanic that does top end work all the time will have a much better ability to evaluate the situation and recommend the best course of action.
Sure would suck to get it almost right, ride a few months and start acting up.

No idea how much damage exists.
If you can lap them yourself, that's a win, IF the lips aren't too thin, seats okay.
Surely a mechanic or machinist would look at it and tell you.
I'm not a newbie. I have lots of tools and I've been in several engines, but nobody ever showed me the things to watch for when doing valves. Just slapping new ones in on worn seats is probably not a sure thing.
Lapping old ones ? The lip of a valve that is thin can hold heat and cause preignition.
That's a pricey place. I had four valves installed and seated for less.
The nearest place might not be your best bet.
Walk in with the head, in a few places.

You have to pull the valves to check them,if they warped ,where ? The stems? or nearer the valves faces ?If the their not straight , lapping may not cut it, you may need to replace them ,and maybe new guides and seals as well as lapping. The valves parts are cheap, I wouldn't risk damaging the head it's not. A slow leak at 14.7 lbs could be much worse at compression/iginition pressures!I'd tend to do it right rather than having to do it twice.

I'm always suspicious of what I have done if I touch something and it gets worse.

Since it leaks on the bench, it's definitely valves.
The cam isn't holding anything open.

The questions you're asking indicate less experience than would be desirable to bet on solving the problem.
Just having a dial caliper and a really flat surface would help you out.
