Good Combo

I have decided to go with the Erson 238/246 @050 621/621 lc 108 I have a friend that is going to give me a set of headers that will fit the frame wells of my truck. I am sure they are not the best for my application but they were given to me. They were bolted to a motor but never started. They are ceramic coated "Rewarder" brand block huggers. When I measure them they have 1-3/4" primaries and 2-1/2" collectors. I am measureing the collector inside diameter? Will these at least work for me or should I just wait and save money for another set? Unsure If I use them and they suck then I would not be able to sell as much as if they were on a unstarted car.
