Debate, Headers, or Manifolds

[piecesparts]

The right design of header will enhance the scavenging capabilities of the exhaust system greatly. If you purchase a quality set, get them with a coating on them, and use teflon tape on the header bolts, they will install and last a long time. I have put headers on my 84 GMC, my son's 86 Chevy, my 2011 GMC, and also on my wife's 95 Impala SS, to top it off, I have a set sitting in my basement ready for my 68 Chevy LS engine. The change in performance was noticeable. However, if all you do is go to the malt shop on Saturday night with the little lady and then to the overlook behind the drive-in, for a few hours, then the stock manifolds are more than enough.

If you go to some of the perfromance websites and look at what many are doing with the different engines in many of the cars and trucks, the gains reported by dyno numbers are good with headers.
