What sound/heat deadener do you like?
Dynamat Extreme on sale from Amazon with free shipping has always been my choice. It's a good start to insulating the interior, but unless you add a double foil sided insulating blanket type material too, you are only doing half the job. I use that wax paper sided foil ducting tape to seal the mat together and hold it down at the seams. I buy my mat from Speedway Motors or Aircraft Spruce.
My '70 E-Body sounds like you are sitting in a bank vault when you close the doors. I did both treatments under the entire interior of the car from the bottom of the front windshield to the rear window, door sill to door sill and under the headliner and door panels. The sound, heat and fumes were dramatically reduced inside the car.
Dynamat or equivalent used by itself is only half the job. It is really only good at stopping panel resonation, but not so much for heat and noise. The mat, properly installed, does the majority of the sound and heat and fume rejection.
