I think I'd like to run valve rotators for perhaps slightly improved longevity. Any idea if these work with the undercut, 1.5-inch Chevy valves?
Other than the four-bolt carburetor mount, is the Mercury manifold any different than the Ford design? Do they flow more?

I bore mine all the way down to the base of the manifold and then round the edges of the transition from the throttle bores. I have no real measurements, but it seems to me that when the vertical passages transition to the
eight passages to the individual ports, a lot of passage volume is encountered.
Take a look down an intake manifold and see what you think.
