I have to agree this time. 
The only time long runners are better is when you are trying to get some naturally aspirated Resonate Ram Tuning effect at lower RPM ranges. There are always piping losses that increase with increase length.

i heard that short runners is better for f.i. plus a decent sized plenum too. i heard the plenum should have half the capacity of the engines displacement. most of the realy high turbo powered cars ive seen use real short runners with a more aerodynamic manifold design. all of those 1000hp supras have a manifold similar to the skyline because the supras stock manifold is restrictive at a certain power range.

St220's runners are tapered which is the main reason why it's superior

After four years of running a shop I never once saw an Expedition or Excursion or Lincoln or Mustang with COP that when one of the coils went, it didn't have anything less than six digits on the odometer.
Hell my Mazda6 was in this so called range of failure with an MSD Stacker 8-channel box supplying power (Something else you guys forgot about in this conversation) to them and they never failed once or even misfired.
