It sounds to good to be true, but if he can do it, that would be great.
I think the Cams are going to be the biggest problem. But with TONs of cash nearly anything is possible.
I've wondered about having the heads ported and polished for a long time, I don't see why that wouldn't do a lot to up the H.P. Port matching to the exhaust too. But of course, any improvement is relative to how good or bad the original design was by the factory.
It would be very interesting to see you make all your mods in steps, and document your performance gains as you go along. I'd save the "wet shot" for last, because I think that's probably the least desirable thing to do by most on the forum. (I know I wouldn't want it).
Good Luck with your plans, I'm sure you will have lots of interested forum members watching your progress.
