Have you insulated the floor and firewall? That stick on reflective aluminum insulation from Lowe's or Home Depot does a really good job.

Insulating the header pipes will just move the hot spot to under the floorboards- - - -where it can REALLY get hot- - - -maybe even start a fire. Good luck! Insulating the firewall would be a much simpler (and safer) choice.

Why not use a product designed for the application,

https://www.summitracing.com/search/part-type/heat-barrier-and-sound-deadening-mats

Yes it works, the size of each piece is large yet small enough to be manageable, on my 46 did my cab interior including firewall, floors, behind seat, behind door panels and a little left over.

I did the firewall inside with stick-on insulation but not the outside. Over an hour or so the whole cab heats up conducted from the firewall which picks up engine heat particularly from the exhaust. In the winter this is s help as I don't have to run the heater after a while. But in the summer.....

So, I wish I'd done the outside of the firewall. I might yet but I wonder if I could get the pieces slid down behind the manifold and head before they stick too soon and make a mess.

The best way to keep heat out of your cab would be to use radiant barrier foil but for it to be very effective you must install so there is a 1 inch gap between the foil and the surface you don't want to get hot. Around 12 years ago we installed that stuff in our attic on the bottom side of the joists & rafters of the roof boards creating an air space between the foil and roof sheathing and the use of electricity for A/C dropped by over 28%. Some of the best money I ever spent. If you want to see just how effective this is, just get a 60 watt incandescent light bulb, turn it on and hold your hand about 2 inches from it. You'll feel heat and it will increase the longer you don't move your hand. Now do the same thing but with a piece of common foil (shiny side facing the bulb) between your hand and the light bulb. You will not feel any heat at all.

I've used Thermo-Tec "Cool-It" mats in two trucks and I like the way it installs and controls the heat...I used a small wall paper seam roller to get it pushed into all the nooks and crannies.
