Usually cast into the top of one of the intake runners.

hey do you no much about that dam , butterfly valve located under the carb, i guess its supposed to direct heat ,for easier starting.i need to no if its advisable to just remove it. or leave it.

thought you might no something about it.

Go ahead and remove it if you can plug the holes, unless there's someone here with dyno/flow testing that shows loss of performance.

I'd advise that if intake and exhaust were separated that when bolted together with new steel gasket you put a straight edge on it, if it's out take it to a machine shop for 'surfacing' while still bolted together.

I would leave it. Especially with an iron intake.

Might boil the fuel when it is warmed up if it isn't deflected.

Not knowing the year of the car 1981 was the first year of non adjustable hydraulic valve train. If they are adjustable, they're suppossed to tick.


Best bet is to go where slant is spoken fluently and frequently.


www.slantsix.org It is time to invest in some books. Get the factory service manual.

If it could boil the fuel it would do it now with manifolds already contacting and baking like an oven........
Never had any issues.

Using my infared thermometer my fuel line on my Dart has temps as high as 182* The factory routing of the fuel line causes boiling of the fuel. With hot starting even in cool weather I needed to hold the throttle all the way open to clear things out. That was on 2 slant cars.

Why wouldn't you want the exhaust diverted away from the intake when it is up to operating temperature?

The addition of 10% ethanol has compounded the problem.

The bi-metal spring diverts heat to the intake stove when its cold and rapidly warms to rotate and deflect the heat toward the exhaust. Prevents iceing of intake but thats never a problem as the intake sits on the exhaust, just aids in COLD weather starts and warm ups. You need it, or block it in the divert (hot) position.
