Tow vehicle upgrade
I have a 95 half ton suburban. It only has 66000 miles on it. I want to do upgrades to give it more power. It has a 350 with 373 gears. I was led to believe a good set of headers will greatly help. So...

if it is a 2wd then a swap to a 4.10 gearset , preferably positraction would be the best bang for the buck .
being a car guy myself , for towing the best route are the modifications that increase the capacity to pump AIR through the engine .
modifications that pump additional fuel through the engine are very expensive in actual practice during towing with $ 3.75 gasoline .
headers are a good method , if you make the swap out to the larger diameter exhaust plumbing behind the headers .
i would also seriously consider a large capacity auxilliary transmission cooler radiator .
aftermarket headers and their gaskets are not able to mainain their seal under repeated high heat conditions such as pulling hills with a 7000 # square box behind .
additional cooling capacity will help mitigate header gasket failure .
