Headers Vs Manifolds - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looking for your opinions. The next thing on my to-do list is to replace
the exhaust system because my old one is rusted and busted. Right now
I run a stock 307 with a crossover single exhaust with stock manifolds.

I am thinking to replace it with a dual 2.25" exhaust, with H pipe, nice
sounding muffs and have it exit right after the rear wheels at a 45 to
give it the nice stock look.

My big decision to make: replace the manifolds with headers, or keep it stock?

Manifolds:
- Stock Look
- Easy spark plug access
- already have them
- Will last forever

Headers
- Horsepower gain?
- Nice looking
- Might be a B*tch to replace plugs?
- Might wear out in a few years?

What do you guys think. Is there really that much of a gain to go to headers?
