Opinions, notes, comments etc. on headers

[67_C-30]

The header brand and construction you choose is very important if you want a leak-free set-up. A cheap header with stamped thin flanges are going to leak - sooner usually than later. A good brand 16 gauge header with thick flanges with the ball socket type collectors are the best way to go, but you pay for what you get. As crazy longhorn said, the gains on a stock engine are far less significant that on a stock engine a modified one. You won't a night and day improvement with just a header change.
