Does all this sound good, or does anyone have a better suggestion.
Sounds good to me, although I suggest getting ahold of a good steel straight-edge and confirming that the intake surfaces are flat.

Be sure to use the correct torquing sequence.

Also, I'd use a thin coat of the Right Stuff around all the coolant passages, not just the front and rear ledges. Be sure and torque it down before it sets up (I'm not sure how fast the "one minute" stuff sets)

Also regarding that bracket, hold off on attaching anything to it until you're sure it's not leaking - just so the weight of a compressor isn't part of the equation.
