Could you do a full block and utilize the pipe insulation as a spacer to allow some air to enter/exit ?

Even a partial block helps - you end up with a high pressure zone and most of the air goes around or over the car, rather than through the aerodynamically very dirty engine bay, then out the bottom (or wheel wells). More importantly, it helps reduce warmup times.
