Cylinders one and six have less intake flow than cylinders two-five. Less air=less power. Normally this small percentage imbalance will not greatly affect power, but in high horsepower, high rpm applications, that small percent starts to equate to a larger part of the pie. When inches can be the difference between first and second place, those few extra ponies could make the difference. For high-end 2.6" truck with all-out cylinder heads.
Cylinders one and Six, 230@.050" .406"/240@.050" .410"
Cylinders two- five 225@.050" .395"/240@.050" .410"
