Good point,

Do you run a cross over? IMO 100* of water temp is not enough. I also think you should have water lines from the front to back on the intake manifold.

Yep! When I had my engine run on the dyno I asked them to put a load on it and run it with a steady state test from 3500 RPM to 4500 RPM. I wanted to make sure we had good A/F numbers in that range, and also wanted to ensure that there would be no oil drainback issues with valley screens installed. While running this way, we saw it go pretty lean and the headers began to glow. If I had simply dropped it in the boat and run it after making several quick pulls on the dyno for WOT power data, I am 100% sure I would have likely melted it down at a fast 4200 RPM cruise.
