So the new IAC did nothing!!!
Fuel rail temp when I got home was average, 95*c intake temp avg was around 110*c, header temp at head was 120*c and at the collector 270*c.
Methinks that with all the venting I have in the hood it's pulling all that heat up around the intake and rail, where as a stock hood will allow the heat to be pulled down and out. At least at any sort of speed.
So...I'm thinking of wrapping the intake and cutting the fins between the ports to allow as much heat as possible to escape, and wrapping the fuel rail. And maybe add a heat shield between the block and header.
Opinions?
