Depends a great deal on where the compression is going, IMO.  If it's going
into the water jacket, you're going to have a hard time keeping the cooling
system full and low coolant is a killer for aluminum engines.  But I've
driven iron engines for a long time on N-1 cylinders (first car was a Chevy
straight 6 that only ran on 5); and the only real problem was vibration and
lack of power.

I'd disconnect it.
