No, you don't want to swap a 929 engine for a 954. The 954 will run hotter and have heat related issues and your cylinders can crack if the heat gets bad enough.
Plus not much more power or speed than a 929.
Just keep the 929 engine and put full exhaust, eliminate the exhaust valve, open the air box all the way, and put a 954 fuel injection system to the 929 engine if you have the $$$$ to do it.
Then your 929 will be more than fast enough.
you don't want a 954 engine, they are bored out too much, not enough material left in the cylinders and between each cylinder there is almost nothing, at least the 929 engine has 1MM more material between each cylinder.

He's right, the 1mm bore is the only dimensional difference in the engine itself. A power commander will make a bigger difference and you can get them under $300. You can also wait until you need a new chain and go -1/+2 on the sprockets. Your top speed will come down, but even on a track you'd need a 1/2 mile straight to really use all 160mph-ish of the stock gearing. I've only topped mine out a few times on lonely highways and with no plastics that last 10mph takes a bit. Plus, I feel like I'm about to fly off the thing...

If you are buying a used engine then I would go with the 954. This topic has been discussed many times and you may find more info on fireblades.org . Keep in mind though that several other parts are required to swap a 954 engine into a 929 if you want to make your 929 just like the 954. You may want to check it all out before you decide which way to go. If you only swap the 954 engine and keep everything else from your 929 you will most likely not feel any difference in how your bike runs.

Your going to ship it from the UK to the state or country of Georgia? Tax and shipping across the ocean can get nasty. There are a few 929 engines on ebay stateside for $800-1000. They do bolt into the frame the same, you'll need to use the airbox/swingarm mount/etc from the 929 since that is the chassis your putting it into.

I've found most people are honest that are charging normal prices. Make sure they have good feedback and that it's from selling bike/car parts, not religious t-shirts. Ask them before you bit what they are going to do it it doesn't run. You could also get a case and a crank, then use your good parts to rebuild an engine.
This one is kinda cheap cause it leaks oil on a crack repair. I'd get it and epoxy/rtv the leak, but I prefer fast and functional over looks.
