Your signature says youre running 800ftlb torque.. that is approaching (if not well-in) the danger-zone for VQ headgaskets. You could be an exception. But if you are looking to stay on the safe side of things, I wouldnt be worried about your intake manifold I would be worried about your headgaskets.

700ft/lb at 4550 RPM and mine were done. It appears the higher the RPM the peak TQ is, the lesser of a problem it is.
