Headliners help with heat/noise????

[one legged lance]

Hello All,
I have my grandpa's 72 C10 and he ordered it farmer style down to the radio delete.
After driving it for a few Phx summers now I am starting to debate a headliner.
Thoughts???????
The inside of the cab roof is hot to the touch with the sun shinning and the noise in our trucks could aways be reduced. The question is will I get that ourt of a Headliner....if so where/what kit is best?
Original or one of those setups with the speakers?
Dynamat type sound deadener under or just the alum foil backed matting?
