I still owe you a ride. By the sounds of the power you are making I can't wait to go for a ride. Actually a bit afraid to run you. Your new motor sounds like a beast. Don't worry about that 10 bolt, she'll last until you race from a dig. 474 rwtq is a lot of grunt. So get ahold of me, I got the itch to run bro.
ya, my stock 10 bolt is going to hate me, 3.42 gear isnt helping out to much either, but we can run em one day

Larger MAF or no MAF
Electric water pump
Shaft mounted rockers
The fact that you exceeded 500 rwhp so easily speaks volumes of how well the L92 heads work. How's the driveability of the car right now? Can't wait to hear about the power once you put the big shot of spray on it.

While I am certainly the last person here who should question Patrick's cam spec for you, and he's helped me a ton too.. I think you would make much better numbers closing the intake valve sooner to avoid reversion and advance the ICL since the L92's runner CC is so large and air velocity is low. Yes, the L92's are very exhaust weak compared to the intake side, but instead of increasing duration for an earlier EVO, you are already advancing the ICL which with the same cam will make the EVO earlier as well (less gas pumping loss since you need more flow out of a smaller hole per say, it will take more craskshaft degrees to accomplish). I'd try a cam with a smaller exhaust lobe and a lot more advance. Something along the lines of a 240/246 112+5 or 6. I think it would work better than a large split. But I also don't know what goals you had in mind for your car, which could influence the cam choice. Patrick's knowledge is indespensable on this site, I just look at the L92 head a bit different. I would take the existing cam and advance it another 4 degrees if I couldn't swap the cam out. I'm not trying to insult anyone, I'm just offering my view.

That is a GREAT NOS CAM.. damn...

I was wrong and I didn't have the all the info.. and I certainly wasn't trying to ruffle any feathers.
