Dynamometer Results & Comparisons - Help with dyno results

I recently dyno'd my car(95 lt1 6-speed, shorty headers) after I had the lt4 hot cam and springs installed. Can anyone give me their opinion on what is going on after 5800 rpm. FYI, it gets noisier when the power starts to drop. Thanks
FYI, I posted this earlier but this time I scanned the dyno results in.

"it gets noisier when the power starts to drop"

Just a guess but maybe valve float?

Looks like you are hitting the stock rev limiter (set to 5850rpm).

I wish it was the limiter, I had the tuner set it to 6500 rpm. Thanks for all the input.
