Can I use newer stock cams to boost my 78 kz1000?

Here is a "simulation" of what you would gain.
1015cc
34mm carbs
Stock head (based on the flow numbers on Larry's site)
Sidewinder header (based on my measurements of my own)
2 stock intake cams(current) vs. stock intake and exhaust(last).
These would be crank numbers, not wheel numbers.
Basically you pick up 1 hp peak (yes, one horsepower!), and a little more "overrev".
It's not much. Stock intake cams are cheap though.
Up to you if it's worth the work. I was thinking of doing the same thing in the past.
Larry: I would love to get detailed dimensions and flow charts for stock heads and ported heads, to use for this.
Garbage in = Garbage out, better data is always...um, better.
Let me know if that is something you have and would be willing to share.
I'll get you some flow numbers. What increments of lift do you need and what starting lift?

By the way... if any of you guys think I'm too cheap to be doing this or I'm expecting a bunch of power for nothing, think again! I've been around long enough to know better. The primary reason I'm tearing this engine down is to make it RELIABLE for more years, NOT to get more power. If I can find an inexpensive way to add a few ponies while I'm at it I'd be happy, but that's not my main objective. So there!
Well that's fair enough
