Plenum and spacers are part of entire induction system, this is where length and CSA dictate where peak occurs.
Guys who port plenums and transitions correctly make power

Re: 2" spacer....waste of time/$$??
Things that suggest a spacer is worth testing:
1. any dual plane manifold
2. large engine for the plenum volume
3. smaller carb CFM than calculations

A spacer will lower the Fuel temperature in the bowls and thus marginally increase power. Might not show on the Dyno but usually picks up a tenth or two on the track.
