I have one that requires dynojet runviewer. If someone could host it I'll send it over; give me an email address.

JMX Looks like your package made some pretty good HP and especially TQ for the age of the heads (over 2 years old?)
Spring change to 977's probably would have helped a great deal

I appreciate your time posting the graphs guys...
I have a dip @ 6K, drops both HP and TQ about 20, then recovers about 6300 and continues to pull on up to redline. From what I am seeing on your graphs, it looks like your motors aren't recovering from the float, rather just falling off completely. My car doesn't do that, it recovers quickly and continues to pull....
Hmmmm.....Me needs to get these 987's off...

So what exactly on a dyno graph shows valve float? I lost 30rwhp on my last dyno on an LS6 with roughly 10k miles, a TR224, and Comp 918 bluestripes. Instead of peaking at 6500 like it did originally, it now peaks at 5200 and flatlines all the way to 6500. I'm not sure what this is.

Springs are harmonic set. No pressure. Terry @ Patriot and I discussed something that was brought to me by one of our engineers here. I am not going to say what it is but after bringing it to Terrys attention he agreed with us it may be the culprit to all of these springs going south and its not the springs fault. I have got a call into someone I trust that does R&D work for the Boys in NC so after that call I will post what we have found.
