Headers VS 340 manifolds

My $99.00 P.A.W. headers worked out great. They were not too difficult to install but definitely more trouble than manifolds. I would suspect they make a fair amount of power compared to manifolds. Changing plugs is not difficult, no mini-starter was required and no right angle oil filter adapter either.

Been on the car ten years and still have plenty of metal left on them.

Manifolds should last forever and if you lean towards the purist side there is absolutely nothing wrong with running manifolds. I am running manifolds on both my 70's Camaros because they would make the floorboards get too hot. Camaro manifolds flow pretty good too. That driver side A body manifold looks like a cork though.

If I was going to run manifolds I would install b-body ones again, they are cheap and they flow. Getting pipes to fit on the driver side is a challenge though.
