: Exhaust manifold clearance problem

Hi,

I have a 350 in my 67 Chevelle. It has high performance aluminum heads with plugs that angle down.

My problem I have is my stock exhaust manifold touches one of the plugs. In the history of the 350 engine was that specific year or years that the engine had plugs on a down angle? I have heard that some later model Camero's had heads like this and possibly different exhaust manifold.

Any leads will be appreciated or ideas would be appreciated.

I just dealt with this on a friend's truck with angle plugs and manifolds. Get the Accel shorty spark plugs and they will clear the manifold enough so the plug boots don't burn.

Bob,
Angle plug heads were never installed on a production vehicle.
