The Econo heads can not be purchased new. There really only worth about as much as someone would pay for new units, if they were available.
Headers, who’s? As long as you realize that no one will pay more for them when they can get them new and have no return issues.
Intake, which one do you have?
Intakes are inexpensive most of the time. Ding dongs on E-gag sometimes want more for there used up greasy garbage than the exact same one still available to be sold new at Summit or Jegs.
