Heads between generations

I want to keep it tight and sweet!

Will the heads from a newer generation fit on a first generation cases?

Why?
Reading some of the other technical postings on here I have found people talking about the abnormal sounds coming from there first Gen bikes.
That it was not all but some to more.
I might have kept the engine in the upper rev limits for a while on the highway!
She can really scoot. The sound the weight power delivery the steadiness! It tracks so well and I can put it where I want to when I want to!
Anyway the other day I went for a tootle and the sound from the top end was not to my liking during start up. I checked the oil and it looks good and feels good. Some machines are known to be chatter boxes I don't want to end up with a off the shelf chatter box because of valve guides. The top end will have to be looked over and IF that is the big IF I do have to replace valves, springs, guides or what not I might as well change out the whole head if applicable for a newer generation head if the heads fit and have a better flow.

Anyone able to answer some of these questions would be awesome!

Your problem is most likely a bad cam chain tensioner unit, causing cam chain noise. Change the cct first before worrying about anything else in the head.

What @Bernie said.

Never run out of ideas, traction, and real estate at the same time.

Absolutely what Bernie and Redfish said. Rattle noises are most likely CCT, ticking can be injectors.
