Mopar 340 intake gasket replacement
I just replaced the intake gaskets on my 318 a couple of weeks ago. I didn’t use the cork gaskets but Permatex Ultra Black instead on the China walls. Depending on the intake manifold you’ll be putting on, you might need to cut off the dowels (one on front wall and one on back wall) so the intake manifold sits properly. Also used a small amount of Ultra Black around the 4 coolant ports between the gasket and intake. On the rest of the intake gasket (both sides) I used gasgacinch.
The 4 intake manifold bolts around the base of the carb will be difficult to take out and retorque properly if you don’t have a 3/8” drive 9/16” torque adaptor. If you don’t plan on removing your distributor, that torque adaptor will also come in handy on the two intake manifold bolts that also support the throttle bracket.
