What's the ONE best internal engine mod?

While I've got my 78 KZ1000 apart, I may just decide to splurge and buy ONE internal engine hop up item with my tax refund.
What do you think is the most cost effective? The most bang for the buck? Cams? Pistons? Porting? I can only pick ONE so don't give me a long list...
The bike has BS34s, Dyna ignition, and Sidewinder drag pipe. All else is stock.
The Dyna is the really basic model that's completely inside the right engine cover. The coils are stock. I've always been a bit skeptical that performance coils really do much, but feel free to tell my why I'm wrong.
So which ONE would you pick?

No substitute for displacement . . . except a nitrous kit.

Ok here's another one for you guys to argue about :laugh:

How many miles are on the engine? My answer will change significantly based on this answer...
Each modification can bring benefit, but in some cases cons too. If this were a commuter bike you'd get a different answer than if it's ridden hard.
Most big bore kits generate extra heat, and require higher octane fuel (more expensive). If you commute in hotter temperatures I'd tell you to steer clear of a 10.25:1 piston kit.
If you plan on just riding on the weekends and having some fun, the big-bore kit is good. I'd probably start with HD cylinder studs and the piston kit. You then have the option in the future to rework the head - either porting it, or just dropping some mild street cams in.
If you are tearing the engine down completely, I would start with the fundamentals - a new Tsubaki cam chain and HD studs - possibly new idler sprockets, cam chain guide, etc. They are more important than the big-bore kit.

Yes I think the cam chain, studs and rollers is a good idea.
